All Apple had to do is make bootcamp and a streamlined timemachine available on Tiger and Leopard is no more.
I have not seen a single successful argument that says Leopard provides some significant, game changing improvement without which Mac development would be stalled.
hahahaha that's an amazing quoteWow, that's like upgrading your VW to a ferrari and then taking it back because you don't like the volume knob on the stereo.
I went back to Tiger now because Nikon Capture NX 1.3.2 doesn't work in Leopard. I work most of the time with this application so I went back. Now everything runs very smooth.
I use Capture NX 1.3.2 with Leopard every day. Works fine for me with images from my D2H and my D3.
Actually, most of the significant upgrades in Leopard are "under the hood" (see below).
How about better process scheduling, better virtual memory handling, sandboxing certain system services like Bonjour to improve security, including DTrace in the kernel to ease debugging, the FSevents API, Core Animation, the Core UI framework, Core Text, code signing, address space layer randomisation, new objective-C runtime etc. Not improvements that are immediately obvious to the end-user, true, but they will all help to drive the next generation of OS X apps.
You are lucky... The Nikon Capture NX site say something about this issue...
Nikon Capture NX v1.3.2 Updater - Macintosh
Precautions:
Capture NX is not completely compatible with Mac OS X version 10.5 (Leopard) after installing this download. There are still certain issues that need attention before full compatibility is possible.
I have a friend that had a lot of problems with his iMac with Leopard
No internet plug-ins available yet for many browser apps - that is a big thing.
In fact, go look for the Internet Plug-ins folder in Leopard - it doesn't exist!
Leopard is also still very 'buggy' - just read the forums. I've had my Dock hide and then vanish , mouse pad issues , wake/sleep issues. Even simple things like dragging a message into a mailbox folder in Mail have caused me grief!!
So, newbies take notice - not all that glitters is gold.
However, you can still use Bootcamp by setting back your system date/time to before then. I usually just roll the year back one and it works fine.I'm a little concerned about bootcamp not being supported past 12/31/2007 under Tiger but other than that I have no reason to migrate to Leopard.
