I first did the "Software Updates" which was ready in a few minutes.When I try the update to Yosemite, though, I get the spinning cursor and it stays that way.I've looked at this answer but I find that the CRL is already set to "off". Ideally, how can I upgrade this machine to Yosemite? I'm trying to install a free utility (Caffeine) and I get the same problem: the spinning cursor, but no actual progress.

I thought that maybe it was just a huge download, so I left it on for the night. I've found the Console Messages, but the only thing I see there is "This isn't a bitmap context.

The next day, after more than 20 hours, I still saw the spinning cursor. An internet search told me to check the "Purchases" tab on the App Store, but for that I need my boss's password. Forcing destination format to ARGB_8 for CG_Context". So - without access to the purchase record of the machine, but with admin privileges, how can I see what is going on?

Always back up a Mac before installing any system software updates.

The Mac will install the update and reboot automatically.

It was released on September 18, 2002, less than a month after the August 24, 2002 release of Jaguar (10.2).

Note that support ended for all releases listed below and hence they won't receive any further updates.

You can find recommendations for the respective operating system version below.

Note that the first generation of Intel-based Macs equipped with Core Solo or Core Duo processors is no longer supported. We provide older releases for users who wish to deploy our software on legacy releases of Mac OS X. Mac OS X 10.4.7 or later is required Use VLC 0.9.10.

Nonetheless, most Mac users are better served keeping things easier by just installing the update through the Mac App Store.
