10/24/2019 Update: I still recommend waiting to install macOS Catalina. In my experience, there are a number of bugs and anomalies in the initial release.
An excellent discussion and advice on waiting to upgrade to Catalina, as well as changes regarding Carbon Copy Cloner and clone backups:
10/7/2019: Apple just issued a surprise release of the next version of Mac OS, known as “Catalina”.
This release breaks older, “32-Bit” application software, meaning some programs will simply not run.
I *HIGHLY RECOMMEND* waiting to update to Catalina and only after doing an inventory of your mission-critical apps to make sure they are 64-bit ready.
***IF*** you do decide to upgrade, make absolutely sure you have a bootable clone backup of your computer BEFORE upgrading to Catalina. Do NOT update that backup for a few days or up to a week after you upgrade, or you won’t have the ability to restore back to your pre-upgrade state.
In a recent set of software updates, Apple has begun asking users if they would like to store the contents of their Desktop and Documents folders in iCloud Drive (Apple’s Dropbox-like repository for files and folders “in the cloud”).
I’m not a fan.
The idea here is to upload everything in these two folders to your iCloud account and keep it all in sync, across multiple computers. While this seems like it might be a good idea, the current implementation has some drawbacks and things to consider before simply checking the box:
- If you have lots of files and folders (i.e. Gigabytes) on your Desktop or in your Documents folders, enabling this feature will require you to pay for extra storage space in your iCloud account. Uploading that much data over your internet connection could take days/weeks. This isn’t clear in the initial setup dialog.
- Enabling this feature means you have to pay attention to whether a document is stored “locally” or “in the Cloud”. For files/folders which are only stored in iCloud, you must be connected to the internet to work with them.
- Disabling the feature isn’t as simple as unchecking the box – there isn’t a simple ‘undo’ command which puts things back they way they were previously. This can be scary because unchecking the box makes everything disappear from your Desktop and Documents folders. The process of disabling the “Documents and Desktop in iCloud Drive” feature requires multiple manual steps to restore the files and folders to their original locations. Here are the instructions:
I recommend against enabling this feature in the first place:
