OS X :: Read Only Ical - Can't Change To Read - Write
I know this is lame, but I searched and can't find a solution. When I click on a day in ical it says it is a Read-only calendar. I repaired permissions, but it still says read only. The strange part is, in the Get Info screen, it says Read-Write for all the users.

MacBook Pro :: Read / Write Permissions For FAT32 SD Card
after a lot of searching in similar threads I have found no answers to my question. I have a MobileLite usb drive that takes various sizes of SD cards. I have inserted into it a 256MB regular sized SD card (that which you would find in cameras). I plugged it in to add a file to a folder I had labeled "apps" and the file was clicked and dragged into the folder on the SD card no problem. I disconnected it (safely) and then reconnected it to add another file. Now it is saying that the SD card is read only.

1) The switch on the SD card is NOT set to lock so I know thats not the problem.
2) I backed up all the files onto my desktop, and then went into Disk Utility to see if I could reformat it, but it wont let me.
3) Under "get info" there are no options to change the read/write permissions.

It is to my understanding that FAT32 should be native for both PC and MAC so I dont know whats going on here. Further more, its troubling me that I was able to write onto the SD card, and after unplugging and plugging back in, I now only have read access.

OS X :: Wants To Change Permissions To "Read All Write All" Globally On External HD?
i used to have a bunch of files on my hard drive before i sold my mac pro

i backed everything up on an external hard drive so i can keep it until i received my imac. now i have my imac, and when i try to transfer over the files to my imac, or another external hard drive, sometimes the copying stops and says something along the lines of "you do not have permission to copy this file"

so i guess some of my files got messed up, putting them in "Read only" mode.

i know i can go to "Get info" and then manually change it to "read and write" mode but honestly theres so many files it would take a lot of time.

is there a script, or an app i can run that could scan my whole external hard drive so it will go thru each file in their own specific folder and change the permissions to "read all write all" without me doing it manually one by one?

OS X Leopard :: Essential Read / Write Permissions?
I hope I don't make a fool out of myself with my first question, but after several hours searching the internet (not sure how to name my problem) for answers I'm just gonna ask: In our office we have several computers connected, each user can drop stuff in each others dropbox. ok. The problem starts with the permissions of the documents. For each document you have to set them to read/write for the staff, which is not difficult, but annoying. So here is my question: is there a way to tell programms eg TextEdit, PhotoShop,... to create all documents with read/write permissions for me AND the staff?

Final Cut Pro :: Read / Write Drive Permissions - Transferring Quicktime Movie Files
I am trying to transfer a few quicktime movie files over to an external and the drive is set up for read only. I am getting a message "This drive cannot be modified" I have been navigating the settings and I would like to find out how to make it so I can write to this drive. In the bottom left of the drive folder there is a pen with an "X" across it. i can log in as an admin if I need to, but that has not helped my case. Is there a section where I can change the drive settings from Windows to Mac? This was my problem another time, but I forgot how to find that option to modify

IMac Intel :: To Change The "Permissions" On An External Drive To 'read & Write'?
I am experiencing a problem with an external Hard Drive that I'm now using with my iMac, that used to be connected to my old PC.

I can't write anything to it. When I check its "Info", under the "Sharing and Permissions" tab, it says "You can only read". how to change this so that I can both read and write to the drive like normal?

OS X Leopard :: Apply Read / Write Permissions To All Shared Folders
My husband and I just switched from PC to Mac in the past month. There are several things we need to learn about the Mac interface. One vexing problem we have is the read/write access seems arbitrarily change to no access for the other user on the network. We have file sharing turned on. The folders we share are shared folders. Sometimes when I create a folder on my husband's iMac in the shared folder and put files in it, he can read the folder and files I have created, but cannot save changes to them. The only way he can save his changes is to save to another folder he has created.

Is there a way to globally apply read/write permissions for all shared folders and folders/files created within shared folders into the future? This situation is difficult to deal with and creates unnecessary copies of files (and confusion) on our network. By the way, if we had known how superior the Mac is vs. PC we would not have chosen to suffer through the PC experience for the past 15 years. We just have a lot to learn about this new (to us) operating system.

OS X Leopard :: Create Default Read / Write Permissions For More Than 1 User?
My wife and I share an iMac, but use separate User accounts for separate mail accounts, etc. However, we have a business where we both need to have access to the same files and both have Read/Write permissions on when one of us creates a new file/folder. By default new files and folders grant Read/Write to the creator of the new file/folder, and read-only to the Group "Staff" in our own accounts or "Wheel" in the /Users/Public/ folder, and read-only to Everyone. We are both administrators on the machine, and I know we can manually override the settings for a particular file/folder by changing the permissions, but I would like to set things up so that the Read/Write persmissions are assigned for both of us in the folder for that holds our business files.

It is only the 2 of us on the machine, we trust each other and need to have complete access to these many files that we share. I have archiveing programs running so I can get back old versions if we need that, so I'm not worried about us overwriting the file with bad info. I'm more concerned with us having duplicates that are not up to date in our respective user accounts. Here is what I have tried so far: ..............

Server V10.5 Leopard :: Read / Write - No Delete Permissions
This should be fairly obvious, but I cannot come up with the correct ACL settings in 10.5/10.6 to create a file share that is read/write to a specific group, but they cannot delete. This is a photo archive that needs to allow people to add files, but not remove them. Seems like unchecking the "Delete, Delete Subfolders and Files" should (leaving Read completely checked and should apply to All subfolders and files.) What am I missing? I'm sorry I don't have more to offer specifics-wise on the server at the moment, because I'm offsite. But here are some details: 10.5.8 Server on Intel Xserve w/XRaid attached. OD Master running internal DNS that resolves back and forth correctly Users connect via AFP, but Bonjour is disabled. Several other shares(folders) on the RAID, but only this one requires this set up. No matter what combination of Permissions I check, logging in as the user(AFP) via Kerberos produces 3 results:

1. User can read/write new files, but can also delete (bad).
2. User can only read, no write/delete (bad)
3. User can no longer see share point.

This seems simple and perhaps I need to try removing the ACL altogether but it seems severe. Can someone create a working share like that and post the screenshot? I can get more specific information next time I'm onsite.

Server V10.5 Leopard :: Set Read / Write Permissions To All Subfolders
So I have a clients folder created on the server, and workgroup with employees setup to access the shared clients folder. You can log onto it from outside, and access the folders. However they all need to be able to write as well; save files, move files, etc. I have the permissions set for the workgroup to read/write on the clients root folder, but it only applies to that folder. Any folders underneath it dont take effect. And there are hundreds of folders and subfolders. Obviously there must be an option so that i the permissions i set to the root clients folder are applied to ALL subfolders! How do i do it?

All my old office files have become "read only" and I cann ot modify and save w/o renaming. Is there a "blanket" way to change the Permissions to "read & write" for all my Office files? Idid not see a similar item in the FAQ's......

Also, when I open an Office application, I get the following message: "An unexpected error occurred while trying to load the Microsoft Framework library". How do I fix that?

Server V10.6 Snow Leopard :: Read / Write Folder / Newly Added Files Read Only?
Our company uses a server to store a shared logo database and work files, and to transfer data from one user to another. At this point, we do not have any need for Read Only on this server; everything should be Read/Write. That's how it was set up initially, and the permissions were propagated. About a year ago, our old XServe crashed and was replaced with a new XServe. I believe our trouble started there, and has since migrated to our Snow Leopard Server: we have several folders where, if an employee uploads a folder and/or file, those files become Read Only. We have to go to the Get Info for that folder and fix the permissions each time. This has to happen up to 20 or so times a day, and I'm the only one who has server access to fix it; it also seems to be affecting more and more folders. I'm not in IT, so this is a little beyond me, but I've been working with IT on this (I'm Mac, he's PC). Can anyone offer a suggestion as to how else we can go about permanently setting the permission to Read/Write on all folders? Server Admin hasn't been successful.

Hardware :: What Format Write / Read And PC Read?
I'm buying an external hard drive to use as a backup for my MacBook but also as a network drive that all the computers connected to my router (Airport Extreme) can use. There are two MacBooks and two PCs that connect to the network. I only need my MacBook to be able to write to the hard drive but I need the two PCs to be able to access and use the files on the hard drive. I was going to get a 1TB external and give it two partitions. The first partition is going to be the Time Machine backup for my MacBook and the other will be accessed by all computers on the network. What format will the second partition need to be so that both MacBooks and both PCs can view and use the files? Also what external hard drive would you recommend?

OS X V10.7 :: Change Mail Preview In Lion From A Vertical Read To A Horizontal Read?
I just switched from Snow leopard to Lion and i don't like the way that Lion has the mail preview set up as a 3 column vertical format. I thought in Snow Leopard you could change the set-up so it's either horizontal or vertical, but I can't seem to find that option in Lion. I want to have the list of my email messages in the top, horizontal window and the preview of the selected message in a horizontal window below. Am I missing this option to change the view format from vertical to horizontal somewhere?

OS X :: "only Read" When Set Privileges To Read & Write
I was trying to write xmp data to my photo's, when I got errors on photo's in certain folders. ?Writing XMP Metadata? did not complete successfully. It seems all jpegs in a few particular folders have generate this error. I then noticed all those files were lacking a creation date. When trying to copy the "image taken on" date to the "creation date", using A Better Attributes, I didn't appear to have the right permissions.

Now this is, to me at least, the weirdest part: when I open Get Info on any of the images, it says "You can only read", even though all privileges are set to Read & Write (screenshot attached). The folder itself says "You can read and write". So far I've only seen this on files/folders on an external hard drive, formatted Mac OS Extended (Journaled). It's a WD My Book, connected via USB through a hub. Anyone ever seen this before? Is there anything I could try to fix this?

MacBook Pro :: Read / Write Performance Of SSD?

I get a screen note saying I can't add anything because something is already on the disc... but it's only one little 3 meg file. But apple i info. shows no room on the cd.

How can I erase the cd and reuse it? I find no erase command and when I try to drag the file to the trash, i get another note saying i don't have permission... even tho I've check off the permission box.

MacBook Pro :: SSD Random Read/Write Speed Survey
There's been a large emphasis on the sequential read/write speeds of SSDs, but in many day-to-day usage patterns, the random read/write speeds are a better benchmark of performance. I'd like to make a chart summarizing all the different SSDs out there and available. But I need your help. Can those of you with SSDs run a benchmark and report the numbers here so that I can compile everything? Here are the steps:

1. Download Xbench 1.3 at [URL].
2. Open the program and run the "Disk Test" for your SSD drive.
3. Note the numbers under the Random test, for all four parameters of small and large writes and reads.
4. Repeat the test a second time to make sure that the numbers do not change. Accept the second test if the values are <10% different from the first test.
5. Screen capture the window by holding down command and shift and 4 and the spacebar. Click on the result window and that will save as a png file on the desktop; the default is Picture 1.png.
6. Report the values here with by attaching the screenshot of the result window. This will give us other needed information like computer and SSD model.

I realize that there are weaknesses to this survey. Xbench is only one benchmark. SSD speeds will vary based on usage. Etc. In the end, however, the variability should be sufficiently small that I think we'll be able to compare different SSDs well.

I'm going to get us started by posting my results with an Intel X-25M on a previous generation MacBook Pro. Ironically, my result will probably get thrown out because the SATA 1.5 GB interface actually limits the SSD read speed...

MacBook Pro :: Paragon HFS+ For Windows Can't Read / Write Flash Drives
I use Paragon HFS+ for Windows which allows me to read and write to my HFS formatted drives. It works great for any external hard drive I use but when I use a flash drive it doesn't work. I format both my external hard drives and flash drives the same way, I use Disk Utility, I format them using Mac Extended Journaled and GUID partition scheme. When plugging in my flashdrive, my Windows 7 PC will not mount them. Disk Manager shows 3 partitions: EFI, Fat32 and some empty space. If I format my flash drives using the Master Boot Record partition scheme they work great.

So, here's what I have so far:External hard drives work fine when formatted with the GUID Partition scheme. (Mac extended journaled) Hard drives also show 3 partitions in Windows Disk Manager: EFI, HFS and empty spaceFlashdrives show 3 partitions but oddly enough the second partition shows as FAT32. But is completely unusable in Windows 7 Flash drives have to be formatted using the Master Boot Record partition scheme when formatting them as HFS+ volumes in order to work on Windows 7Windows 7 supports GUID partition schemes.

What is causing my Macbook Pro to treat an external hard drive differently then a flash drive when formatting them? Experience and common sense tells me that it shouldn't matter whether it's a flash drive or spindle drive, both should format the same. Granted, I could simply use exFat or FAT32 on my flash drives for cross platform compatibility however I prefer to use HFS+ when possible.

Suddenly I am only able to read though. I go into the "Get Info" pane and the option to choose whether I want to read and write, or read only is gone, and all that it says is "You can read only". getting this back to read and write is really appreciated. I really need this disk.

MacBook Pro :: Disk Repair Is Taking Ages To Read Permissions Database?
I had posted a few days ago about a problem with my optical drive not burning through Toast or any burn software except finder and itunes. Lately, the softwares either reported errors, quit unexpectedly, froze and even caused kernel panics.

So I thought of using disk utility to repair disk permissions, maybe something went wrong because I know for a fact that the optical drive is fine as long as it burns with other options.

I attempted verify and repair disk permissions but each stays ages to just do "reading permissions database".

My HD is a western digital 500GB that was replaced upon purchase of my MacBook Pro at apple in Egypt. So I know it's something reliable and done properly.

All apart that is going fine except this issue with Toast burning and the inability to do a repair/verify disk.

MacBook :: Why Can't Read Or Write From My External Hard Drive
I recently borrowed my brother's laptop to use as a media station for listening to music from, and watching movies, in order to free up some space on my main macbook. In trying to migrate some files over, I discovered that my hard drive, a 320 GB WD Elements drive, is having some problems which I've never encountered before. It has always worked fine in the past, but now I can't transfer any files to or from it, from either computer.  In all of my troubleshooting, I've gotten various errors, (-36, -50), and various messages saying how the device can't be read or written from, or how some files contian unreadable data, etc.Disk Utility found an unused node when verifying the disk, and notified me that the disk needed to be repaired.I then used Disk Utility, which said it was able to successfully repair it, but the same problem remains, and after verifying the disk, it still says it needs to be repaired.I've tried to find any files that may be causing the problem, and was finally able to delete a seemingly troublesome file that was stuck in my trash bin from the external drive after trying various apps, (ie Trash It, Cocktail, What's Keeping Me?).This didn't end up solving anything...I've used terminal to eliminate some other potentially problematic files, with no luck still, and I'm not too confident with Terminal so I don't want to be messing around too much without more guidance.

I've used Disk Warrior to try to solve the problem, but still with no success.When I use the app to Check All Files and Folders, it does so for only a few seconds, then reports that "An unexpected error ocurred while attempting to perform file operations" for several files, and that several files' "Property list is damaged and cannot be repaired".  When using Disk Warrior to REBUILD the drive, the app pauses for about 15 seconds, then says that it can't be rebuilt because it is in use.Again, I've used the What's Keeping Me? app to kill any activity with the drive, and the same error occurs.I've spent a lot of time trying to sort this out.

However, recently I notice my mac become very slow, got rainbow wheel even when i open the safari. then I use the black magic to test the hard disk speed, it appears the read and write speed is only a little over 30mb/s.

i have recently change my keyboard at apple store, I notice my mac slow down after that, do you think it would related?

Mac Pro :: Boot Drive - Read And Write Speed Differences?
My Mac Pro came with a 500GB boot drive when I ordered it 3 years ago.  It has been used most days and now runs Snow Leopard (for scanners and a canopus video box that don't work with Lion) and Lion. I did a write & write test on the drive recently at both were approx 60 - 65 MB/s.  I have another drive in my machine I bought last month, replacing an WD drive that failed in less than 18 months. This new drive (complete same as replacement is a WD Caviar (Black) 1TB 64Mb drive. This drive tests at speeds for 110MB/s.  This may seem an obvious question, but will I notice much difference if I swap the drives around and have the newer drive as my boot drive. Also, does having two OS on a HD slow the drive down also?

MacBook Air :: Flash Drives Can Handle 10,000 Read / Write Cycles Before Failing
Does anyone know about this. I just read an article about a new technology by IBM. IBM breakthrough means 500,000 song iPod - [URL]

Anyway, I have a MacBook Air with a flash drive and this kinda bothered me. In this article it states that:flash drives can handle 10,000 read/write cycles before failing. I was under the assumption that this was not the case and you didn't have to worry about the Flash drive failing over the traditional spinning optical HD.

Does anyone know anything about this? What does 10,000 Read Write cycles mean to me in the real world. Is this 1 year, 5 years, 10 years, what..... When is it reading and writing, isn't that pretty much constantly?

I did a google search on this, and couldn't find any real useful info on this. Also did an Apple Support Search and couldn't find anything about this either. the search came back with zero results.

Information:
G5 Dual 2 GHz +MacBook Air Flash
Mac OS X (10.5.2)
