Well, I spend yesterday and part of this morning preparing my current MacBook Pro 2.66 (June 2009) for the upgrade to OS X Lion
Was going to wait but decided to go for it.
Had no real issues with the upgrade, however I had my system ready to go before hand.
I am happy to say I am now running under OS X Lion and it is running smoothly.
It takes a little time to get use to the new options like what the Magic Mouse can do and with the Pad using your fingers. But it is cool.
It does now work in full 64 bit mode which means it takes full advandge of your ram.
Mac Mail looks a little difference, but once I figured that out it was no problem.
Time Machine also worked as it has already backed this system up.
No problems that I can tell with Lightroom or Photoshop CS5. Also have Aperture on this system and it ran ok. However I have not printed anything as of yet.
Now I did print some text to the HP L7780 with no problems.
The Firewire 800 drives I have connect to the NitroAV Hub http://www.nitroav.com/product/113/
all work with no problems.
So overall I had no real issues. It took about 45 minutes to down load the update (about 4 GB) and about 33 minutes to install.
If you follow: http://www.macworld.com/article/160943/2011/07/get_your_mac_ready_for_lion.html
you should have no problems.
Since I do use OnOne software they informed me to deactivate
before installing Lion.
