Problems restoring OS from Time Machine

[meddyliol]

I have just installed the new OS El Capitan, and at the moment I don't like it. I want to restore back to Yosemite from my Time Machine backup. I restarted, pressed CMD R and it then showed a lock and appeared to ask for a password. I put in the password used to install software etc but it did nothing. I am at a loss now as to what to do.

Any help or advice would be greatly appreciated

Thanks

You have to download yosemite and use diskmaker X to create a bootable USB of it and install from there. Once you upgrade you can't downgrade from a time machine backup.

Attach the Time Machine USB drive then hold the option key at boot and select the TM drive to boot from. Once win the TM disk based recovery screen use Disk Utility to erase the entire internal disk to Mac OS Extended (Journaled). Then quit Disk Util and click restore. You will get a screen like this where you can pick a restore point that still had Yosemite and restore.

This will put Yosemite and all your data and apps from that date back on the drive.
