Well, I have done some limited tests and so far, not too bad:
Photoshop runs (that’s a good sign!)
My disk heavy Photoshop action runs faster under Leopard:
(average of 3 runs)
Tiger = 143 seconds
Leopard = 110 seconds
Thats quite snappy.
I cannot print to my Epson 3800 printer until sometime in November when Epson will release an updated driver (thank heavens I can print using my Vista PC!). Other Epson printers are effected including the 2400 more details here: Epson
You will need to re profile your monitor after you install Leopard
If you use bootcamp to dual boot windows don’t forget to go into windows and load the latest drivers from the DVD.
From my limited tests it would appear that Photoshop runs a little faster when running Photoshop tasks that are disk bound (swap,loading,saving) so that’s a plus point.
Other potential reasons to upgrade? well, to be honest not many, look at the new features and see if your convinced.
Visually things seem less clean and lack the old Mac “purity” it looks more cluttered and busy like Windows Vista.
If you need to make prints in the next month on an Epson inkjet then don’t upgrade just yet. There may be other problems, I will report back if I find them. In the meantime check out other reports on Leopard on the internet.
