I'm trying to install a free utility (Caffeine) and I get the same problem: the spinning cursor, but no actual progress. The problem seems to be with the App Store. So - without access to the purchase record of the machine, but with admin privileges, how can I see what is going on? Ideally, how can I upgrade this machine to Yosemite?

I've looked at this answer but I find that the CRL is already set to 'off'. Forcing destination format to ARGB_8 for CG_Context'. I've found the Console Messages, but the only thing I see there is 'This isn't a bitmap context. Brandneu Original Apple Mac OS X 10. I do have admin privileges on the machine. An internet search told me to check the 'Purchases' tab on the App Store, but for that I need my boss's password. The next day, after more than 20 hours, I still saw the spinning cursor. I thought that maybe it was just a huge download, so I left it on for the night. When I try the update to Yosemite, though, I get the spinning cursor and it stays that way. I first did the 'Software Updates' which was ready in a few minutes. The 'About this Mac' gives me the following information:

So you can run a newer OS just not the latest depending on what you currently have.Īpple removed all of the 32-bit OS code in Mountain Lion which is why you can't run it.I have an old Mac, currently running Mac OS X 10.6.8 'Snow Leopard' that I must upgrade to OS X 10.10 'Yosemite'. However, although it has a 64-bit processor, it has a 32-bit EFI and is not capable of booting into 64-bit mode. This system can run the last version of OS X 10.7 'Lion' if upgraded to at least 2 GB of RAM. Upgrading from OS X Snow Leopard If you’re running Snow Leopard (10.6.8) and your Mac supports macOS Sierra, you will need to upgrade to El Capitan from the App Store first.

The Core 2 Duo models can in fact run Lion (10.7.x) sorry to say it can't run Mountain Lion. You need to install an intermediate upgrade first.

The older Core Duo's CPU is not 64-bit clean which is why they can't run Lion or Mountain Lion

However, it cannot boot in 64-bit mode nor does it support 'OpenCL'. This system can run the last version of Mac OS X 10.6 'Snow Leopard'.

Weighing in at 719MB for desktop computers, and around 430MB for notebooks, the update is available for free download via the Mac OS X built-in Software Update mechanism, and from Apple's Support Downloads section. The Core Duo group can only run up to Snow Leopard: Apple has released the long-awaited third incremental update to its Snow Leopard operating system, Mac OS X 10.6.3.Verify your model going to EveryMac - Lookup plugging in the last three digits of your system. While Apple's TN imply this model won't run Lion or Mountain Lion there is in fact two versions of this model group the older Core Duo and the newer Core 2 Duo.
