That&rsquo;s a stark fact, that we&rsquo;re now at the point where the more cautious should consider whether they&rsquo;ll run 10.15.<\/p>\n<p>[&#8230;]<\/p>\n<p>The upshot is that there are going to be many Mac users who simply can&rsquo;t risk upgrading to Catalina, and will be stuck running High Sierra, whose support is expected to end later this year, or Mojave, whose support should expire in just over 18 months. Apple needs to reconsider whether its current support policy is realistic if there&rsquo;s a growing number of users of currently-sold Macs who are stuck running older versions of macOS in the future.<\/p>\n<p>[&#8230;]<\/p>\n<p>For many users, the drawbacks in Catalina are largely the result of Apple becoming over-extended: Catalina runs best on Macs with hardware specifications that Apple marketing isn&rsquo;t yet prepared to make the baseline for models such as the iMac.<\/p>\n<\/blockquote>\n\n<p><a href=\"https:\/\/macperformanceguide.com\/blog\/2020\/20200201_0744-AppleCoreRot-macOSCatalina-performance-losses.html\">Lloyd Chambers<\/a>:<\/p>\n<blockquote cite=\"https:\/\/macperformanceguide.com\/blog\/2020\/20200201_0744-AppleCoreRot-macOSCatalina-performance-losses.html\">\n<p>Photoshop benchmarks are consistently a little slower to a lot slower (15%).<\/p>\n<p>I always follow a strict procedure\/protocol to get consistent repeatable results and there can be no mistake about this downgraded performance.<\/p>\n<p>Because there are two changes (macOS and Photoshop), I don&rsquo;t know if macOS is to blame, or Photoshop, or both.<\/p>\n<\/blockquote>\n\n<p>See also: <a href=\"https:\/\/mjtsai.com\/blog\/2020\/01\/28\/macos-10-15-3\/#comment-3159443\">philux<\/a>.<\/p>\n\n<p><a href=\"https:\/\/macperformanceguide.com\/blog\/2020\/20200131_1812-AppleCoreRot-macOSCatalina-update-displays-screwed.html\">Lloyd Chambers<\/a>:<\/p>\n<blockquote cite=\"https:\/\/macperformanceguide.com\/blog\/2020\/20200131_1812-AppleCoreRot-macOSCatalina-update-displays-screwed.html\">\n<p>Today, I received a new 28-core Mac Pro and it fails to be able to update to 10.15.3 repeatedly as part of the Migration Assistant process, WiFi or Ethernet.
