In my own experience, I found that Mojave (10.14) was where it started to get a bit painful. the 680GTX), but then also DosDude's patcher is doing a lot of things to keep this rig going at that point.īig Sur presumably does not work on the 2008 machine. This is "UNreasonable" because video performance is heavily impacted unless you get a top-of-the-line aftermarket video card (e.g. The UNreasonable end-of-line is Catalina (10.15). As well, you can get away with most video cards at this point.

"Reasonable" in that you don't need to do much other than upgrade the Bluetooth module to make it work and the performance is acceptable.

The reasonable end-of-line is High Sierra (10.13).

This version of macOS will happily install on a 2008 MacPro. The official end-of-line is El Capitan (10.11). Now that being said as someone who squeezed every ounce of usefulness out of one, I can state that you can pull one seemingly as modern as Catalina if you use dosdude's macOS Patcher. To provide a somewhat definitive cap statement to this question, as of November 2021 the MacPro3,1 (2008) is really beyond obsolete in the modern macOS world. These days, that's just the recovery partition on my Time Machine drive, but 10.6.8 doesn't have a recovery partition.įor belt & braces, I'd clone your exiting drive using something like Carbon Copy Cloner then remove it, so it doesn't cause confusion. I've never managed to get a 3,1 to boot from USB I've always needed a ready-prepared second HD. I would also make sure you have a tested, bootable, recovery path should anything go wrong during the update. Be certain you have an up to date backup & be prepared for the fact that a large number of your existing apps, if they are the same age as the OS, will also need updating. I would, however, be wary of such a long jump in one go. I have one here running just that.Īs of Sierra, 10.12, the above still remains true, yet further clarified - El Capitan is the final OS to support the 3,1 The Mac Pro 3,1 Can quite happily run the current OS X - at time of writing El Capitan 10.11.3.
