I would like to get some general updated advice regarding installing OS X v10.7 Lion. I am currently running Snow Leopard v10.6.8 and am quite happy with it.
However; I purchased, back in October 2011, a OS X Lion v10.7 USB stick. I have yet to install it because I read about a lot of negative issues. Or maybe I just interpreted that they were negative?
I have only one "third party" SW - ClamXav which runs fine with Snow Leopard. Everything else is Apple SW.
So, my questions:
1) What is the latest, regarding stability and issues for OS X v10.7 Lion? Experience/Opinion-wise, is it in good shape to install now?
2) The version on the USB stick is v10.7. I assume if I install it from the stick, that SW Update will get me to current level. Is that correct? Is that version level still v10.7 or v10.7.x?
3) Is it necessary or just recommended, before I update to Lion, that I do a "bootable clone" of my current setup? If so, can someone point me to a "solid" set of instructions to do that?
4) I read, just recently, about the new, upcoming OS X Mountain Lion. Can I skip Lion and wait for Mountain Lion (install Mountain Lion from Snow Leopard)?
5) RE: Snow Leopard. Is there a cutoff point/time that Apple will not support Snow Leopard? Or, another way to ask the questions is, can I stay on Snow Leopard forever (If it ain't broke, don't fix it)?
I apologize for all the questions and thanks in advance for the help and advice!
Yes, the TM backup will enable you to recover in case of an accident or other "disaster." You should also have the original OS restore discs handy just in case, as well.
A clone and a TM backup are a bit different in functionality. While both methods create full-disk backups only the clone is generally bootable. The TM backup is not. Which you rely in is entirely up to you, although, clone backups are not generally incremental like TM. In my opinion neither one is better than the other, just as long as you have current backups that you make sure are working periodically.
Before I install a major update like this I will ensure I have a current TM backup and do a clone of my HDD just in case. But I like redundancy. This is not necessary for everyone, and I would suggest that you having a current, up-to-date TM backup will be sufficient.
