Before you upgrade to the new macOS Mojave - think about what apps you use and the apps that will no longer work in macOS Mojave. Don’t update until you are. But some macOS 10.14 users experiencing sporadic streaks of black screen display would like to think otherwise. A black screen after 10.14 update might occur as an occasional booting problem that’s befuddled many-a Mac user. However, it’s no more than another common macOS 10.14 issue that can be resolved with simple troubleshooting procedures. A MacBook may become slow after updating to MAcOS 10.14 due to some pending updates for some apps. As the new MacOS is rolled out, several third-party apps are being geared up to match the spec and performance requisites of the new MacOS update.
This is a series of tips that cover Mac OS X client edition. Server forums cover Mac OS X server on the community.

September 13, 2021, an updated Safari 14.1.2 was pushed via Apple menu -> About This Mac -> Software Update.
is an article I wrote that everyone updating their Mac should read. No update should be ventured into with operating systems or software without first ensuring your data is backed up in two separate places. Slowing down of your Mac should not lead you to assume an update will fix everything. First isolate why your Mac is slowing down or crashing before installing anything new.

Go to Apple menu -> System Preferences -> Date and Time and select the closest time server to set your time, and do so. Download based on manual time may fail, especially on older systems where the system time is not set right.
Be forewarned, Macs with solid state drives will be updated in formatting to APFS with 10.13 or later (this is discussed later in the tip, but bears repeating). This means if you need to downgrade the machine, you will need to erase the partition with the older HFS extended GUID to use the older systems. Regardless of which direction you go, backup your data first. This is only for Macs older than September 25, 2017.

10.14.6 Macbook Update
10.14.3 was released January 22, 2019. Note, some users are reporting 10.14.3 will not successfully apply as an update without an SMC reset as described how to do in this link: https://support.apple.com/en-us/HT201295
Frequently both updates and upgrades will require multiple reboots to successfully apply. Do NOT become impatient if you find the screen go blank during the update or upgrade process. If you press the power button to shut it down while it is rebooting for the update or upgrade, it may quit the process, and leave you stuck.

The SD card reader in the MacBook Pro 13' early 2015 no longer reads directly in the Finder under Mojave with a card formatted under a Panasonic FZ80. I found I could use the application Image Capture to read the card. What happens in the Finder, is instead of a generic floppy disk icon, I get a generic document icon. At least Image Capture is a work around.
Note: the 2020-004 security update for Mojave has a bug with the screen saver getting stuck. To repair delays in the screen saver, 'The workaround is to choose a non-picture screen saver such as Flurry, Message, etc.' (special thanks to community member dialabrain for this report.
