Secondly, there are 6 more recent versions you could install: Mountain Lion - OS 10.8.x Mavericks - OS 10.9.x Yosemite - OS 10.10.x El Capitan - OS 10.11 Sierra - OS 10.12 High Sierra - OS 10.
How can i update my mac os x lion 10.7.5 install#
Install the new OS to a separate partition, so there is always a roll-back or escape lane should (god forbid) anything go awry). First off, you are running OS 10.7.5, which is Lion.One suggestion I would make (as with all upgrades) is one of two routes prior to any upgrades: During or immediately after the migration, the file above should be removed, so the migration will live happily on the unsupported hardware. There is a small gotcha to this, is that you need to install Lion to a supported platform first (such as a Core 2 Duo), then migrate that installation to the unsupported platform. That tells me its the logic board logic is 32bit i.e. It seems that the only thing preventing a Lion installation on a 32-bit platform is a hidden (from the system, or available through Terminal) file that can be removed: This system can run the last version of OS X 10.7 'Lion.' It is not supported booting into 64-bit mode when running Mac OS X 10.6 'Snow Leopard.' The clue is - 64-bit mode when running Mac OS X 10.6. Though you should take a series of steps before upgrading to Mavericks, if you do nothing else back up the Mac with Time Machine. Now, not being one to give up on these things lightly, a little investigation reveals a simple method of getting the installer to run and upgrade this hardware. As soon as these are removed (from Software Update and the like), then the solution will falter. The OS X 10.11 El Capitan upgrade is available only at the Mac App Store, which means if you have versions Snow Leopard 10.6.7, Mavericks, Yosemite, Lion, and Mountain Lion, the Mac App Store already exists on your computer. This solution works, as long as binaries included with the OS include 32-bit. The discussion here is actually about supporting 32-bit vs.
