Time Machine Ī number of under-the-hood changes were made to Time Machine, the backup software. The Game Controller framework adds support for two major console game controllers: the PlayStation 4's DualShock 4 and the Xbox One controller. Sidecar requires a Mac with Intel Skylake CPUs and newer (such as the fourth-generation MacBook Pro), and an iPad that supports Apple Pencil. With Apple Pencil, the device can also be used as a graphics tablet for software running on the computer. Sidecar allows a Mac to use an iPad (running iPadOS) as a wireless external display. On-device machine processing is used to offer better navigation. Users can give detailed voice commands to applications. The system runs on its own read-only volume, separate from all other data on the Mac. Activation Lock Īctivation Lock helps prevent the unauthorized use and drive erasure of devices with an Apple T2 security chip (2018, 2019, and 2020 MacBook Pro 2020 5K iMac 2018 MacBook Air, iMac Pro 2018 Mac Mini 2019 Mac Pro). Mac apps, installer packages, and kernel extensions that are signed with a Developer ID must be notarized by Apple to run on macOS Catalina. It is designed for building device drivers in userspace, outside of the kernel. DriverKit is a new SDK with all-new frameworks based on IOKit, but updated and modernized. DriverKit Ī replacement for IOKit device drivers, driver extensions are built using DriverKit. Catalina will be the last version of macOS to support legacy system extensions. System extensions run in userspace, outside of the kernel. There are 3 kinds of System extensions: Network Extensions, Endpoint Security Extensions, and Driver Extensions. System extensions avoid the problems of Kexts. Apple demonstrated several ported apps, including Jira and Twitter (after the latter discontinued its macOS app in February 2018). Screenshot (succeeded Grab since Mojave)Ĭhanges System Catalyst Ĭatalyst is a new software-development tool that allows developers to write apps that can run on macOS, iOS and iPadOS.News (only available for Australia, Canada, United Kingdom, and United States).This requires using a patch to modify the install image.

But when your computer has so many small quirks that it's barely usable, you should cut your losses and look into a replacement machine that will perform much better. Little problems, like your charger not working unless it's in just the right spot, dead pixels on the display, stuck keys, and crackling speakers aren't necessarily signs that you need to replace your Mac. You can live with a few odd issues if they don't impact your ability to use it properly, but eventually, something big will go wrong and you'll have to decide whether to fix it or upgrade. An old computer is often a lot like an old car. And as discussed above, it doesn't make a lot of sense to pour hundreds of dollars into an old or even obsolete machine when you can get a new one that will last longer.īarring a major hardware catastrophe, a long list of small issues can quickly become a big problem too. In these cases, your computer is unusable until you get it fixed or replace it. ![]()
