Can I use Time Machine to revert back to old IO X?

[purplemma]

I am having lots, and lots, of trouble with Yosemite on my 2011 MacBook Pro - Safari seizing, iCloud kicking me out constantly until my password gets rejected (am having to reset my Apple ID every day), and everything is soooooooo slow.
With none of the benefits of the new OS X, except that it looks pretty.

Will Time Machine reinstall whole previous operating system, or am I stuck with this nightmare until I finish uni, get a job, pay off all my debts and buy a new laptop?

Cheers for any help you can give - I am so not a tech person!

Welcome to the Mac Forums.

Sorry to hear about your plight with Yosemite. It's such a beautiful national park...

Seriously, you can not directly go back to your old version of OS X whatever it was. Time Machine will restore all your data but it can not restore OS X as TM backups are not bootable.

You would need to erase your hard drive from Recovery, download your previous version of OS X from the Mac App Store and install it fresh. Afterward, restore your TM backup. If you need further help on this, post back to this same thread.

Darn! I thought that might be the case. I've had a look in app store for Maverick (my last version) and Mountain Lion, but all roads appear lead straight back to Yosemite? Apparently Apple aren't allowing users to choose OS that actually works on their computers :-( As much as it pains me to say anything nice about Windows - at least you could just reload from the disk if you needed to!

Thanks for your help

Did you upgrade or clean install?.
I had some problems after upgrading but a clean install fixed them all.

Looks like Doc posted just before me with the same question..

I am having to many issues myself and considering reinstalling, but this time doing a clean install.

Despite my acute computeromania, I can't claim great expertise: my elderly iMac (with a youthful SSD installed) had aches and pains at first with Yosemite, but seems to be recovering... perhaps a bit slow at downloading. Yosemite seemed to have torpedoed Photo Shop CS5 until I simply put in the disk and told it to reinstall PS. The other Suite products were unscathed by Yosemite. The graphics of Yosemite are such that I couldn't conceive of going back to earlier Os's.

To find Mavericks at the MAS, click on Purchases tab and all of your previous purchases will appear. Mavericks installer should be there, even thought it was free.

Just out of interest I checked previous purchases as I have just upgraded to Yosemite (happily) and all I found there was Yosemite and no sign of Mavericks my previous o/s.

Will Time Machine reinstall whole previous operating system,

If you made a complete backup with Time Machine, you can Restore from Time Machine while booted in Recovery mode.
I just did it myself this past week. 100% recovery of files and preferences.
