OS X V10.7 Lion :: SSD Boot Drive Permissions Not Correct
Apr 18, 2012
I tried running blackmagic design's disk speed test on our Mac pro ssd boot drive only to be told that the drive was read only. looking at the disk info I saw this:
admin: r&w
system: read only
wheel: ro
everyone: ro
I changed system to r&w to allow me to use the disk test. I would have expected to see (me) somwehere in the access list but I'm not there and I can't add myself. Is there a way to rest the drive's permissions to the default settings? Or what is the best solution to wipe the drive and start over?

Internal hard drive crashed, could not repair. Lion installed on external boot drive, using Forklift to recover files. Cannot access the files of other users from internal drive. How di I change permissions on the internal old boot drive so I can recover the files? Â

The fans of my mid-2010 quad core mac pro speed up to sound like jet engines. The machine can be running all day or for less than an hour. The number of applications in use range from 1 - 5. The activity monitor always shows the finder using the most resources. About this mac says all of the ram is good. The hardware test says all if fine. I have reset the machine by unplugging it for few minutes.
There is one thing that is problematic and I do not know if affects the fans - the permissions are not correct. When I run repair permissions it returns a large number of 'acl found but not expected' and frequently changes the permissions so only the system can 'read or write'. Then I have to manually change them to what I need.

I have a new MacBook Air running Lion. Every time I use my backup software, it changes the permissions on my external drives, and I have to change them from read only to read & write, so I've gotten in that habit. At one point, I noticed that the permissions on my internal *startup disc* were read only, so I (foolishly, I now know) changed the permissions on the startup disc to read & write, with apply to all enclosed items checked. As I continued working, I got messages that a number of extensions could not be used and will be disabled (or something like that). I decided to reboot, so the computer could reset and hopefully correct things.
When I tried to boot, it hung up on the grey screen with the Apple logo and the spinning clock/gear. I let it spin for a while, then forced power down and tried to boot in safe mode. The progress bar appeared as it's supposed to, but when the progress bar finished, it went back to the grey screen and hung up again. I let it spin for over 40 minutes before powering down, just in case it was doing diagnostics or something. I don't have access to the original OS DVD (nor do I have an optical drive to put it in). Any way for getting the computer to boot, at least in safe mode?

I have recently upgraded my computer. My external hard drive, a LaCie 320GB, is full of stuff that I want to get rid of. Can't delete it. Looked into the permissions and it turns out they belong to an unknown user. I tried clicking the little lock and trying to change permissions, but it will not let me interact with the drop down menu. Â
I believe there is a terminal command to reset permissions locally, however, I cannot figure out how to do so on an external drive.Â

I found a strange glitch with file permissions when accessing a network drive, on Lion. I am accessing my internal drive on my iMac over Wi-Fi from my MacBook. I am logged in under my user name. I notice that for every file on the remote drive (on my iMac), "staff" and "everyone" are ready only, but read & write access is reserved for "macports". Macports? It does not list my own name as having read & write permissions, and so I cannot save any file to this remote drive. When I access the drive locally on my iMac, the permissions appear correctly for the same files, i.e. my own name is listed as having read & write access. Is there some kind of glitch where the file permissions are misread when accessing a drive over the network?

I just bought a new 27" 3.4GHz i7 iMac to replace my agin iMac running Snow Leopard. Every time I turn the sharing on so that I can access the iMac and the attached hard drives from my other computer all the permissions explode to in infix able stse where I have to flatten the drive and reinstall Lion. I've spent hours on the phone with Apple, troubleshooting, running bits of code in the terminal all with the same result which is the permission going ****** (including bad .kext files) Any ideas out there or should I just go for a replacement iMac?

Last week I finally upgraded from 10.6 to 10.7, but now my Mac Pro (2008) won't boot properly. It'll start to boot with the gray screen and the Apple logo, but then the entire screen goes gray and it just locks up there.  However, if I reboot and hold down the Option key to bring up the list of bootable drives that works fine. I've checked my Startup Drive settings and the proper drive is selected. why it won't boot on it's own anymore? Holding down the Option key is getting old.Â

I have an IMac with Mac OS X 10.5 on it. Here is what happened: I wanted to network my imac with another pc in the room that has Windows on it. I set permissions to allow read write access for other computers on the network. The pc on the network were displayed on the imac but could not be opened when clicked on. Message box stated needed to reboot imac.
On rebooting the imac all that comes up is grey screen with apple symbol and gear running underneath it. Tried booting in safe mode-screen displays progress bar.Progress bar completes and then goes away and then all i have is a grey screen with an apple symbol and rotating gear. Also tried resetting the PRAM which ended with same result of grey screen,apple symbol and running gear. Have recently moved and can not find my install disc.

First off, I am very O.C.D when it comes to my electronics and I constantly worry about my stuff. Over the past month, I have been checking SMART status and benchmarking my hard drive at least once a day. I'm a little worried that my hard drive is dying... Yea, I'm crazy...Regardless of the above, I would like some answers to a few questions..First, how durable are the unibody lower case screws? Do they strip easily? If I purchase the correct size screw driver (phillips #00), what are my risks of damaging the screws, or possibly wearing them out prematurely?Second, how difficult is it to realign the lower case and not cause a "wobble." I have read some people incorrectly screwing in the bottom case and basically bending the lower case, causing the machine to wobble on a flat surface.After reading my manual, Apple clearly indicates that users are permitted to service the hard drive. I'm technologically savvy but my only worries are damaging my $2500 machine...

I am unable to boot lion from an external drive on both a MacBook Pro mid-2009 and an iMac late 2008. Both have lion installed and I would like to boot from either a FW drive or USB key. I have reformatted both a FW drive and USB and set them to GUID and installed lion but I can only boot them to the Disk Utility App (drive shows up only as 'EFI Boot' when I hold option down).Â
The firmware is up to date and I also reset the PRAM. I am able to boot both computers from an external USB Snow Leopard drive.

I have just installed a 240GB LaCie Little Big Disk Thunderbold SSD as a boot drive for my 2011 iMac (which contains only the 7,200 prm HDD). This has improved read/write speeds dramatically. I have transferred all my data and applications to the external drive in order to see the full benefit of the SSD.
However, I had not considered Time Machine. I thought it would simply be a matter of identifying the external drive and then connecting to the Time Capsule. However, the external drive is not visible in Time Machine set up and I suspect there could be a good reason: that it is not possible.

So I'm having problems with my setup, and looking to find a possible remedy. I have setup my Mac with a 120G SSD in my main drive bay, and moved my 750G HHD to an optibay setup. I booted off a USB copy of lion to install it on the SSD, used migration assistant to move my things over. Â
So currently it boots off the SSD (named Boot Drive), has a "boot user" with its home folder on the SSD, and has my old user (lets call it "olduser") on the orignal drive HDD (called Optibay) and I created a new user when logged into the "boot user" with the same name "olduser", and moved its home directory to the old HDD path, /Volumes/Optibay/Users/Olduser. Then I deleted everything except the user folder on the HDD.Â
BUT, I'm having spin up issues, and constant read/write on the HDD in the optibay even on the boot user, and at times it shouldn't be. I have moved my files around enough that I can now fit the "olduser" onto the SSD, (moved the contents of Movies, Pictures, Documents, and Music folders into new folders @ /Volumes/Optibay/Myfolders). Â
So how do I move the home folder/user from the HDD to the SSD. I can't quite figure out the best way to do it with preserving all my settings and everything that is at the root level on the HDD to the SSD. Trying to preserve permissions seems to be the biggest issue. Should I be logged into "olderuser" and copy the user folder onto the SSD, then login to the boot user and just change the home directory path to the new one? Or should I be logged onto boot user when I make the move? The end goal is to make the optibay drive ejectable while running on my olduser account so I can get it to spin down

Prior to upgrading to Lion I used SuperDuper to create a copy of the existing internal hard drive on an new external drive (iOmega eGo 500GB). Tested booting from the external disk and it appeared to work correctly. Upgraded to Lion. Several days later attempted to boot from the external disk (by setting the start up disk in the system preferences) but it fails. The system always boots into Lion.
What I've tried: Setting the start up disk through system preferences. Holding down the option key to select a disk on startup - interestingly enough I only see the internal hard disk and a recover HD. No sign of my external disk. Using a clean partition on the external hard drive I installed SL from the retail DVD. This produces the same effect of system booting to Lion on the internal drive, which suggests that the problem is not related to the copy I made using SuperDuper, but rather has to do with the external drive or something in Lion that prevents using an external drive (but I've never heard of such a thing).

I'm looking to wave good bye to my MacBook Pro running Leopard and upgrade.Â
However, I need to keep a version of Leopard so I can run certain Audio Units that won't run on Snow Leopard or Lion.Â
I have made a bootable drive with Leopard on it, but I can't get it to boot on my iMac running Lion. It boots fine using the MacBook though.Â
Is what I'm looking to do possible any more, or do I need to configure the drive for use with a Lion machine somehow?Â

I've been hearing good things about the Spinpoint Drives and the 750GB ones are coming down in price.Here is my current setup1 - 500MB Drive - Leopard2 - 320MB Drive - Vista 643 - 500MB Drive - FAT32 (Shared, Irrelevant)I plan on replacing drives 1 and 2 with 750GB Spinpoint drives.My question is, can I boot off of the Leopard dvd and put in Drive 1 and NewDrive1 and just clone it, and do the same for Drive2 and NewDrive2 and clone it? And then go into Leopard and resize the HFS partition, and go into Vista and resize the NTFS partition?

I constantly use Mail to send and receive emails on my MacBook.On it I have three email 'accounts' - my me.com address (for formal emails to work, banks etc.), my "junk" address (for spam, gaming etc.) and my "home" address (for personal emails and everything else).When typing an email, if I choose to send it from a different account than the one I originally selected, I can just change it in the 'From' pop-down menu (under the 'To', 'Cc', 'Bcc' and 'Subject' fields).Recently though, for some reason when I want to send an email from my "home" address, it sends it from my "junk"one instead, even if I am sending it 'From' my "home" address.It still has my "home" address' signature, and not every time it does send from my "junk" one instead - rather it seems to send from both as it feels up to.This bothers me quite a bit, especially when I send an important email using my "home" address but it sends from my "junk" - both confusing and annoying me and the recipients.This only just started happening to me this past week.

I'm trying to boot up my late 2013 15" MBP (shipped with Mavericks) using an external startup disk running Mountain Lion. I really need to use the FCP iChat Theater feature, as I need to do some long distance editing. The startup disk works just fine, I checked it on another computer, but when I restart my Mavericks mac and choose it as the boot drive, I just get a grey screen with the universal "no"symbol (circle with a slash through it).
