I decided to test every MacOS operating system that was not supported by this machine using the OpenCore Legacy patching tool.  In one case (Mojave) I used a similar patch from a fellow who goes by the name &#8220;dosdude1&#8221; on YouTube and elsewhere. By the way, <strong>the last officially supported version of OSX for this was machine was El Capitan<\/strong>. So, I tested the following:<\/p>\n<ul>\n<li> Sierra (worked with OpenCore patcher)\n<li> High Sierra (worked with OpenCore patcher with a hiccup &#8211; throws an error when it attempts to verify, but, works fine)\n<li> Mojave (<strong>failed<\/strong> with OpenCore patcher but <strong>worked with <a href=\"http:\/\/www.webputzer.com\/wp-content\/uploads\/2023\/08\/macOS-Mojave-Patcher.zip\">dosdude1&#8217;s patcher<\/strong><\/a> &#8211; internet had to be disconnected and date set to 2018)\n<li> Catalina (<strong>failed<\/strong> with OpenCore patcher but <strong>worked with <a href=\"http:\/\/www.webputzer.com\/wp-content\/uploads\/2023\/08\/macOS-Catalina-Patcher.zip\">dosdude1&#8217;s patcher)<\/a><\/strong>\n<li> Big Sur (worked with OpenCore patcher)\n<li> Monterey (worked with OpenCore patcher)\n<li> Ventura (worked with OpenCore patcher after I bought a decent quality USB thumb drive&#8230;..<strong>after numerous previous failures!<\/strong>)\n<\/ul>\n<p>The installations that went smoothly need no explanation.  I watched a couple of YouTube videos, patched the installers, the patched versions were written to external USB devices and everything went smoothly.<\/p>\n<h2>The Problematic Installs<\/h2>\n<p><strong>About High Sierra:<\/strong> When I ran the OpenCore Legacy patching tool on High Sierra it would write to my USB for quite awhile &#8211; writing about 5-gig &#8211; and then would stop with an error message that thing had failed.   This was driving me nuts and I run the thing eight or ten times with different USB devices.  I finally noticed that while the program displayed the message, &#8220;ERROR &#8211; Failed to create macOS installer&#8221; there was also some text at the bottom of the thing that said, &#8220;Patcher (501:6200) Done.&#8221;  Here&#8217;s a screenshot:<br \/>\n<img decoding=\"async\" src=\"http:\/\/www.webputzer.com\/wp-content\/uploads\/2023\/08\/Untitled-1.png\" alt=\"ss\" \/><br \/>\nI decided to just reboot the computer and see what happened if I tried to install from the failed USB installer &#8211; I thought maybe I would, somehow, get a clue as to what was happening.  After all, the thing said it failed but it also said that the patcher was &#8220;done&#8221; &#8211; whatever the hell that meant. Anyway, <strong>the USB which had supposedly failed to be properly created worked just fine to install High Sierra.<\/strong>  For reasons that only a smarter person could ever figure out apparently what was failing was the following: When you run the OpenCore patcher it writes for awhile and, then, validates what it&#8217;s written.  Apparently the darned thing was writing fine, but, when it reached to validation portion the thing had a problem. Was the drive suddenly locked&#8230;.had Jupiter aligned with Mars?  I have no freaking idea.<\/p>\n<p>Again, for whatever reason it was failing when it hit the validation phase but it was apparently being written completely and with no errors.<P><strong>About Mojave:<\/strong>. As noted above this would not work with the open core legacy patcher but worked with dosdude1&#8217;s tool with the following caveats:<\/p>\n<ul>\n<li> The date, during the install, must be set to 2018 (I used &#8216;date 010109452018&#8217; &#8211; I actually recall the exact date), and\n<li> You must disconnect from the Internet during the install routine.  Why? I have no idea.\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>So I had this old, early 2009 Mac Pro (single processor variety) and I beefed it up with RAM (32-gig) and an SSD drive.
