Apple released macOS 10.15 Catalina on October 7th, and like all major operating system releases, Apple has been talking it up since it was introduced at the company\u2019s Worldwide Developer Conference in June. It will feature new Music, TV, and Podcasts apps to replace iTunes. A new Mac Catalyst technology will make it easier for developers to make their iPad apps available for the Mac. Photos, Reminders, and Notes all get major upgrades. Screen Time has migrated over from iOS. And Sidecar lets you use an iPad as a second screen or graphics tablet with an Apple Pencil.<\/p>\n

Sounds great, doesn\u2019t it? It will be\u2026 eventually. We are upgrading non-essential machines right away so we can become more familiar with the ins and outs of Catalina, but our recommendation to you, right now, is simple:<\/p>\n

Do not upgrade to Catalina until we give you the go-ahead.<\/b><\/p>\n

We know you want to play with all the new features, but Catalina, even more so than previous major macOS upgrades, is not something you should install right away. The reason is that Apple changed Catalina in some fundamental ways that could break your essential apps or workflows. Here are the issues that cause us to recommend delaying your upgrade:<\/p>\n

32-bit apps don\u2019t run anymore:<\/b> Macs have had 64-bit processors since 2006, macOS has been gaining 64-bit support since 10.6 Snow Leopard, and Apple has been warning developers for years that old 32-bit apps would stop being supported at some point. With Catalina, that time has come. To identify which 32-bit apps\u2014and portions of apps\u2014won\u2019t work in Catalina, download and run the free Go64 utility<\/a> from St. Clair Software. If you rely on any of the software it calls out\u2014pay special attention to Adobe apps\u2014you\u2019ll need to update (which might be expensive), find an alternative (which could be expensive and requires learning a new app), or run the app in a virtualization environment like Parallels Desktop or VMware Fusion (which adds cost and complexity).<\/p>\n

\"\"<\/p>\n

Catalina runs in its own read-only volume:<\/b> To increase security and ensure that an attacker cannot subvert macOS itself, Apple changed the disk structures under Catalina. Now, instead of having one main volume that contains both macOS and your apps and documents, Catalina runs in its own read-only volume. Some behind-the-scenes magic makes the Catalina boot volume and the main volume look like a single volume. This may cause scripts that access files stored in newly changed parts of the directory hierarchy to break. It will also likely mean that backup apps like SuperDuper and Carbon Copy Cloner will require updating to be able to backup and restore data properly. Never upgrade before your backup app is 100% compatible!<\/p>\n

Newly installed apps must be notarized by Apple:<\/b> Notarization is an automated process that Apple uses to verify that an app distributed outside the Mac App Store is free of malware. It\u2019s not optional\u2014in one statement, Apple said, \u201cMac software distributed outside the Mac App Store must be notarized by Apple in order to run on macOS Catalina.\u201d However, the company has also said that notarization requirements don\u2019t apply to previously distributed software. It\u2019s likely that older apps already on your Mac when you upgrade it will continue to work fine, but if you try to install an older, unnotarized app on a Mac running Catalina, that may not work.<\/p>\n

Apps require more permissions than before:<\/b> In the last few versions of macOS, you\u2019ve probably seen apps asking for permission to do things like access data in Contacts, Calendars, Reminders, and Photos, or be able to use the camera or microphone. In Catalina, apps will have to ask for permission to access files in your Desktop and Documents folders, iCloud Drive, and external volumes. Plus, you\u2019ll be prompted before any app can capture keyboard activity or a screenshot or screen recording. That\u2019s good for security, but it\u2019s possible that older software won\u2019t know how to ask or won\u2019t work properly if you deny its request.<\/p>\n

\"\"<\/p>\n

Kernel extension installs require restarts:<\/b> Kernel extensions are often necessary for third-party hardware peripherals or for apps that need particularly low-level access to the operating system. Installing one requires giving it permission in System Preferences > Security & Privacy > General even now in Mojave, and in Catalina, you\u2019ll also have to restart your Mac. Call us suspicious, but we won\u2019t be surprised if problems ensue from these new security requirements, coupled with the read-only boot volume forcing kernel extensions to run from a new location.<\/p>\n

Unanticipated backward-compatibility issues:<\/b> Here\u2019s the scenario. You upgrade to Catalina, which requires an update to some app you rely on, call it WhizzyWriter. Unbeknownst to you, the new version of WhizzyWriter requires a new file format for its documents, and older versions can\u2019t read it. But since you can\u2019t upgrade all the Macs in your office because some still require 32-bit apps, you end up in a situation where you can\u2019t easily share WhizzyWriter documents within the office anymore. Yes, we\u2019re paranoid, but we\u2019ve seen this sort of thing happen before.<\/p>\n

Apple\u2019s OS release schedule has been troubled this year:<\/b> There\u2019s one final reason that Catalina doesn\u2019t give us warm fuzzy feelings. In recent years, Apple has shipped all its operating systems on the same day, or at least without significant delay. This year, in less than two weeks, Apple has released iOS 13.0, 13.1, 13.1.1, and 13.1.2; iPadOS 13.1, 13.1.1, and 13.1.2; and watchOS 6.0 and 6.0.1 for the Apple Watch Series 3, Series 4, and Series 5; along with tvOS 13. For devices that can\u2019t update to iOS 13, Apple also pushed out iOS 12.4.2, and for the Apple Watch Series 1 and Series 2, which won\u2019t get watchOS 6 until later this fall, Apple released watchOS 5.3.2. Plus, HomePods are still using iOS 12.4 and even iOS 13.1.2 and iPadOS 13.1.2 still lack some promised features. Finally, the new Reminders app can\u2019t share data with older versions after you upgrade its database, which means that you can\u2019t take advantage of its new features until you upgrade everything to iOS 13 or later and Catalina or later. Frankly, it has been a mess.<\/p>\n

Traditionally, we\u2019ve recommended waiting until the .1 or .2 update of macOS before you consider upgrading. However, with all the trouble Apple has had shipping this year\u2019s crop of operating systems, and all the problems that Catalina\u2019s changes could cause for you, we suggest that you wait for the 10.15.3 or 10.15.4 update, or get in touch with us early in 2020. By then, Apple should have a stable release, and we\u2019ll have a good handle on how to work around whatever of these issues you might encounter.<\/p>\n
