You can have several volumes in a container that dynamically share the space allotted to the container, which means you don’t have to allocate storage space to a given volume beforehand. Each container has one or more volumes, and each volume (starting in High Sierra) has a “role,” which defines the kind of volume it is. APFS divides a disk into one or more containers (similar to partitions). Not only must you use Big Sur to back up to an APFS-formatted Time Machine volume, you can’t even access the backups from a Mac with Catalina or an earlier macOS version installed. This might go without saying, but I know enough people with mixed-system setups who will ask. I would set up any new Time Machine volume formatted with APFS, but not convert an old one from HFS+.īig Sur APFS-based Time Machine backups can’t be used in Catalina or earlier releases. Looking forward to hearing from your ideas.While APFS has advantages for SSD-based storage, there really aren’t any for hard disk drives, the most likely kind of drive used for large-capacity backup drives. Then in this forum, I found a similar opinion in this post:Ĭould it be that I have the same problem too? HEEELLLPPP PLEASE!!! Currently, I am writing this post using the computer with the mechanical drive installed since I need to keep working, but I know that something is definitely wrong.įrom research, I read that maybe the HD SATA cable is gone bad. So now I now that my old SSD is fine and the problem is inside the computer. Installed the new SSD and guess what… Spinning beach ball of death. I bought a Samsung EVO 860 1 TB Today I cloned the info. OR something was wrong with the computer per se. So I guessed that maybe something in the SSD was defective but the different tests were unable to detect the fails and maybe the disk was unable to work internally. The SSD only worked fine inside the computer in Target Disk Mode, or in the external case. I downloaded Catalina as recovery and the same behavior. Extreme slow booting, Beach Ball of Death at login screen with 2 or 3 characters of my password… Useless. So I erased the SSD, cloned the info again, installed SSD internally again…. With the old mechanical disk, the computer works fine. I installed the old mechanical disk, then used carbon copy to clone the SSD… and guess what. Then I used this to boot the old computer. I removed then the SSD and installed it in an external case. So, the SSD seemed to work right with the other computer. Then I booted the old mac using this * MacBook Pro 13" Unibody Mid 2012 2.5 GHz in Target Disk Mode using the FireWire cable and it worked perfectly!!!! But, nothing else related to SSD or memory. I then restarted the computer in Diagnose Mode and showed something that I know: the battery is old and I must change it. I tested the disk with Disk Utility and showed no errors. ![]() I performed several tests:įirst I used the Target Disk Mode and used a FireWire 800 cable to connect the computer to my old MacBook Pro. ![]() ![]() So, I concluded that my SSD drive (OWC Mercury Extreme) was broken. If I tried to scroll down a page I was able to do it for max 2 or 3 seconds and then I have to wait around 30s to 1 min to continue. In the beginning, I thought that was my Internet connection, but then I discovered that the computer slowed down to the point of being not usable at all. Last week while I was watching Netflix, the streaming got suddenly interrupted.
