You would also have to purchase Mountain Lion from HERE (you would not need Lion if you do that) Those are the only choices that you have to upgrade directly from Apple, unless you want to update to the El Capitan (which would be a big leap for you, mostly because of your software needs) Or, you could ignore Lion, and go to Mountain Lion (OS X 10.8.5), which I think would be a better match, and closer to current system. THEN, with Snow Leopard, you have the App Store, where you download and then install Lion. If you don't have Snow Leopard, you will need to purchase that installer DVD, which you can get HERE. You need a Mac that has an App Store, which means that you have to upgrade to Snow Leopard first, then fully update to 10.6.8 (as the installer by itself does not have the App Store, you have to install, then update through Software Update. You have to purchase Lion, which you can get at the Apple online store from here.īut, the purchase will give you a redemption code that you use in your App Store. If you want to try an upgrade to Lion, there's two methods to get there (assuming that you don't already have any newer OS X installers, and have not purchased any) The main reason I ask about this, is that an operating system upgrade will provide newer versions of Safari, and you will have the opportunity to use other, more up-to-date web browsers that you might prefer, and the upgrade should let your browsing experience improve, hopefully, with better security, too. A newer Core 2 Duo can even be upgraded to 10.11.3, depending on what you have - although you may not want, or need to do that - it is still an option for youīut, I need to know which iMac you have, and the System Profiler will tell me everything relevant about possible upgrades for your iMac. What is listed next to Model Identifier? (should be something like iMac9,1 - but I need to know what your iMac shows)Ī Core 2 Duo iMac can be upgraded to Lion (OS X 10.7.5) as a minimum. That will bring up the System Profiler, where you can look at the hardware configuration (Hardware Overview) That window will show processor speed and memory installed (plus a couple of other items), What Mac do you have, and how much RAM memory is installed? You can make sure about that by going to the Apple menu, then About This Mac. Is there a particular reason that you have chosen not to upgrade your operating system? You would be better served if you upgrade your OS X, as you will have a lot of other options. That solution that I posted, with the PPC version of a nice web browser, is designed for those that want, or need to stay with PPC versions.

Those cannot be upgraded to any newer OS X version The usual reason is when using a PowerPC Mac, such as a G4 or G5 Mac.

Sorry - I assumed that you had to stay with 10.5.8.
