AppleStore installed new HD onto my computer. Unbeknownst to me they put on Snow Leopard. Upon bootup at home I selected the "restore from time machine backup" option. After 4 hours, computer rebooted with all of my logins. Looks good, right?!
Passwords are ignored. Apparently, the issue relates to the fact that my data back up is based upon my "old" Mountain Lion OS from the previous HD.
Call into Applestore and they were clueless how to resolve and they had me contact AppleCare. Spoke with tech who ultimately put me on with a "senior tech" I have a single 10.6 disk as well as a single 10.6.2 disk. I think the HD is running 10.6.7or 10.6.8. I do NOT have a bootable disk (only the single install). She was stumped, put me on hold for atleast 10 minutes when the line went dead. (She verified my return number twice). I haven't heard back and am very frustrated.
I feel like I'm in an Apple Catch-22.
Please, any advice?
Follow these instructions for reinstall 10.6, you will need to erase the ENTIRE drive by selecting the drive makers name and size on the left while booted from the 10.6 disk that came with your machine as this is the machine specific version with your free iLife included.
If you use the white 10.6 disk, (it's 10.6.3) then that doesn't have the free iLife, but if you later purchased it from AppStore it can be redownloaded when you get to 10.8 again.
(ideally that older machine should stick with 10.6.8, but you have your files already in 10.8 on the TM drive, so...)
Make sure you erase the entire drive with the Security Erase Zero All Data option, this will "pre-map" off any potentially failing sectors on the drive before they fail with your data on it, it makes your machine a lot more reliable.
Once that's all done, log in and setup with your same user name as before (important) and Software Update to 10.6.8, log into AppStore and hold the option key down and click on Purchases, redownload 10.8 and install.
Revisit and redownload other software like iLife etc.
Use the TM drive to bring back copies of your files into their respective folders.
Reboot the Mac holding the command and r keys down, use Terminal and enter resetpassword, a window appears, select your boot volume and user, then reset ACL's, should fix your user permissions issue.
Note: What the AppleStore should have done is installed the 10.8 Recovery HD on your new drive, then you could have just reinstalled 10.8 from that.
