With File Vault ON are time machine backups encrypted?

Image
I have been using time machine to back up to a wireless external drive since I got my mac. Today I used filevault to encrypt my hard drive. Will this affect how Time Machine backs up my files?Will the new backups be encrypted on the external drive? I am running Lion on the mac. I found this on an apple support page - http://docs.info.apple.com/article.html?path=Mac/10.6/en/21241.html 'If you must back up to a network or external disk that’s not under your control, you can turn on FileVault to encrypt data stored in your home directory. This data will also be encrypted in the backup. However, Time Machine will perform backups only when you are logged out of your user account.' How can I check to see if the Time Machine backups are actually encrypted?
No, the backups will not be encrypted automatically, but it's very easy to enable for directly attached disks. Just check "Encrypt Backup Disk" in the Time Machine disk selection settings. If you're backing up to …

How does Apple's Power Nap interact with File Vault?

Apple has announced that all programs in the next release of its operating system must be notarized. Beginning in macOS 10.14.5, all new or updated kernel extensions and all software from developers new to distributing with Developer ID must be notarized in order to run. In a future version of macOS, notarization will be required by default for all software. How will this affect programs written in Python? Will they need to be notarized? Or will notarization be required for using certain APIs? How about browser plug-ins? Will they require notarization?

I'm starting to research this to better understand its implications as well, since I installed a number of 3rd party apps on my laptop and never use the store. Everything I install is either DMG or via brew. Background & Python For starters I would suspect any applications that are in binary form would be what Apple's referring to when they executables have to be notarized. A Python script, though executable, is not technic…

Will having too many running programs slow down my Mac?

If I have movies, music, document, Photoshop...running on my Mac. I wonder to know whether they will slow down my Mac. I use Magican to monitor my Mac, it displays the programs are take high CPU usage. If they will slow down the Mac, should I need to cut down some process?

No matter what platform you are on, if you have multiple programs all running at once, they are using resources and therefore yes, will slow down your computer. There is a big difference between many applications running, versus actively doing something. For example, if you are watching a movie, playing music, and working in Photoshop, all are actively using resources and the system will have to share them. If you are not actively using something, the a large amount of its resources are given back to the OS, and therefore while still running (and consuming resources), they are not consuming as much. For example - on a Mac you can close all the windows of an application, and most of its resources are released, but it…
