How do I erase mountain lion developer preview and go back to Lion 10.7? I do not have lion or data backed up on my AirÂ
I need a step by step instructions since I have never done this before, willing to set up partition if needed.
Info:
MacBook Air, Mountain Lion
I replaced a 1 TB external drive partiotioned in 2 with a 3 TB extrnal drive run/store my corbon copy cloner back up and time machine.
The 3 TB drive was successfully partitioned through the disk utility and both back ups are installed and the initial back up is complete.
My question is about the 1 TB drive. I want to completely erase all data from the drive in order to use it for a different use.Â
Using disk utility one of the partitions deleted without incident when following the same protocol the second partition produced error messages.
Volume erase failedÂ
Volume Erase failed with the error:
Couldn’t unmount disk.
If I try to eject the disk
It says it will not eject becaus e a program may be using it...
The only program that utilized this partition is Carbon Copy Cloner which is not being utilized on the new 3TB drive.
I do not see where there is a option to have more than on disk chosen for this purpose so am unsure why the disk utility is seeing the old partion as still in use.
I was having problems with the external drive where I store my Time Machine backups, so I tried plugging and unplugging the drive but could not mount the drive. I ran Disk Utility and tried to verify the disk, which told me the disk needed to be repaired. I tried to repair the disk only to get an error message that Disk Utility could not repair the disk and it needed to be reformatted. So I tried to erase the disk with Disk Utility only to get the error message "Volume erase failed: Media kit reports not enough space on this device for requested operation". I am not sure what else to try at this point and could not find any similar questions here. Â
The drive in question is a 3TB USB Seagate Backup + Desk Media, formatted as Mac OS Extended (Journaled). It's divided into two partitions, one of which (2.2 TB) holds only Time Machine backups of my desktop and laptop and the other of which (800GB) is formatted similarly with some files stored on it. I was able to verify and repair this other partition. I'm running Disk Utility 13 on an iMac (2.8 GHz Intel Core 2 Duo) running OSX 10.8.5Â ...
I'm trying to dual boot my Macbook Pro (2010) with Windows 7 to run some software that is not Mac compatible. I have encountered one problem after the next, but most recently, my disc drive has stopped reading discs. I had originally gone from Mountain Lion to Mavericks as an upgrade, and my disc drive worked fine - but due to an issue with the Windows 7 installation, I had to completely wipe my computer and start fresh - booting Mavericks from the Cloud directly. This appears to have knocked out my disc drive and try as I might, my computer will not only refuse to read external optical drives, but it will accept discs, not read them, and repeatedly spit them out a few seconds later. Â
I was looking for a solution - and I'm not sure exactly which route to take. I could downgrade to Mountain Lion and hopefully restore the functionality of my disc drive to install Windows 7 and upgrade my OS after the fact OR I could find a way to repair my disc drive. The issue is most definitely software and not hardware. Â
Ideally, I'll walk away from this with a partitioned MacBook Pro with both Windows 7 and Mavericks installed. I don't even necessarily need my disc drive to work once Windows 7 is installed. Â

I have been using Preview to view and fill in PDF forms. The font that Preview uses to fill in the forms is very small and difficult to read. I would like to make it larger to match the document font size.

why hitting spacebar no longer previews fonts/typefaces. It worked as of last Friday (today being Monday). I have restarted many times, repaired permissions, used FontNuke to clear caches, and have also cleared/relaunched Quicklook caches with the
-qlmanage -r
-qlmanage -r cache
-commands in Terminal. Â

I am not using Time Machine as Genius Bar at the Apple store told me it was best not to (I was continually having errors and so GeniusBar erased my hard drive and reinstalled Lion). They said to then manually drag over documents onto my hard drive, avoiding the Applications, so no possible errors could be dragged back onto the clean hard drive.
But now I have Mail and none of my folders and previous accounts. Of course I can re-setup my accounts, but then they will just try to redownload all of the millions of emails I had before. None of the very organised folders I previously had, sent messages, etc, etc.

I tried to open a single image in Preview (Version 6.0.1 (765.4)). Instead, it opened just over 500 images (out of 2300 on the hard drive) as "Untitled 1" "Untitled 2" etc. Over three hundred of those were grouped in a single window (that is, one of them was visible large, with thumbnails of all in the "drawer"). Why it opened the files as "Untitled", nor, in fact, why it opened them at all. I had only clicked on one to open it. I quit Preview, but upon reopening, all the "Untitled" images were back. The same thing happened when opening Preview after restart. The only way I could get rid of them was to close their windows one at a time. Of course, when closing something that's unsaved, the computer asks whether to save it or not, but I cannot click Command-D (as in previous systems), I have to click the Don't Save button each and every time. This takes ages with so many windows open.Â
Well, since I had no choice, I did that for the couple hundred images that had opened in their own window(s). Then I tried to close the images in the single window. I would do Command-W, then click Don't Save. The dialog closed, but the image didn't go away. Then a new Save dialog box would open with a different "untitled" number specified, and I would do it again. And again. And again. The images, however, did not disappear. Then I saw that the names (Untitled 101, Untitled 204, etc) of some of the images I had previously attempted to close were coming back again. They had not actually closed. I could not get rid of that window with three hundred images open in it. If I quit Preview, then reopened it, ALL of the 500 plus images opened again, even the ones I had successfully closed. The application is now useless until I find a fix.Â
I have an iMac with two accounts (say A and B), where A is Admin and B isn't.
I have a MacBook Air with one account (say C), where C is Admin.
Both iMac(A) and Macbook Air(C) share the same iCloud userID, but iMac(B) does not.Â
By using the built in screensharing service of Mountain Lion (not Apple Remote Login), can I use "Back to my Mac" to remotely log in iMac(A) from Macbook Air(C) when outside of my home network? In particular, can I "log in" iMac(A) when it's not already logged in on my iMac or iMac(B) is using the machine?

I want to download apple developer tools XCode on my iMac, but it says I need a later version of OSX. What are the downsides to installing the later version (Lion?). I currently have OS X version 10.6.8 on my iMac and it says I'm required to install version 10.7.3 or later. By the way, is the updated version provided free or do I have to buy it? I'm looking to do all of this so I can start to develop an App for my iPad..

I just got a new MBP and it is my first. It came with OS X Lion 10.7.3 and I have it updated to 10.7.4. Now with the latest OS X soon to be released, I am thinking of updating it. So my question is that when I do the upgrade, do I need to do it as fresh install? Or, can it be done similar to as an update to existing OS? I guess I would like to know what is the best way to get the latest OS installed on my machine.Â
Not to mention, though I am still learning my way around with the Max OS, I am very much liking the MBP. Any cool apps I should use, please let me know.Â

I got a new macbook pro. I tried installing windows on it via bootcamp...To cut a long story short, I messed up the system. Now the PC doesn't start and when I run the system, the apple logo just shows with the chime. Nothing more. I din't back up anyhting.Â
If the system manages to start, immediately I log on, the computer logs itself off again. Im simply tired of all this and want to erase mac osx lion from my mac book, then re-install it again. How to go about it?Â
I know pressing Command +R then going to recovery will open recovery. Then I click on disk utilities. But then, selecting which hardisk to format?
My hard disk had no partitions, but then trying to format it, I see a larger disk with a different title, then under it, I see "Macintosh HD". Which of them should I select to format to do the job? the main HD or the sub one under it "Macintosh HD"Â
I totally hate this, considering the fact that I have to buy about $60.0 worth of credits to re-download osx lion from the net. My macbook didn't come with a cd you know..

Whenever I try to install the latest preview of Mountain Lion, it says"Some features of OS X Mountain Lion are not supported for the disk "R2iMac". The warning directs me here: http://support.apple.com/kb/HT4649 It seems like it'll let me continue, but once it restarted it eventually said the installation failed. The point is I do have a Recovery HD and I don't know what to do about this.

I am currently running version 10.7.4 from what I read and what I was able to make out from my serial number I wont be able to upgrade from Lion to Mountain Lion as it says my imac is a late 2006 model.I am just curious if I am able to run Lion why Apple isnt supporting the older models that can? Seems odd to me and it is not in my budget to buy a new mac and my current one is running perfectly. I'm not sure how much I will miss out not having Mountain Lion.

I inadvertently deleted my OSX 10 Lion operating system on my Mac Mini -- tried redownloading it but continually received an automated response saying something like ".... unable to download the software, try again later"  That is not an exact quote but close. I tried several times to download the software but always received the same message. I did verify that WIFI was up and working properly on my separate laptop.
