instal the new version for mac Eldest Souls

There have been at least two further firmware updates for that model since, with 10.15.3 (and Security Updates) taking it to 175.0.0.0, and 10.15.4 (and Security Updates) on to 176.0.0.0. Readers here reported this problem, and I posted an article which questioned what was going on. Those iMacs should have been updated from version 170.0.0.0 to 173.0.0.0 when upgraded to Catalina, or with the matching Security Update for those which remained on High Sierra or Mojave. Since the release of the first version of Catalina six months ago, one particular model has resulted in a worryingly high failure rate in firmware updates: the iMac Retina 5K 27-inch Late 2015 (iMac17,1). It’s not as convenient, perhaps, as being able to run a separate firmware installer, but works. When this happens once, it’s no great disaster, and applying the update a second time – perhaps in the ‘Combo’ updater – often does the trick. Occasionally, though, updaters don’t install the firmware updates they’re expected to. You let Software Update download and install macOS updates, and whenever new firmware is released for your particular model, that gets updated too. When everything works well, you shouldn’t have to worry about any of this.

Old versions can have incompatibilities with more recent releases of macOS (or Security Updates), and may contain security vulnerabilities and other bugs. Keeping your Mac’s firmware up to date is important. Each such update now comes with installers for the current release versions of firmware, which are different for various models of Mac. For some years now, the only way that your Mac can update its firmware is when you install a macOS update – which includes both updates to macOS as a whole, and Security Updates for previous major releases of macOS.
