I haven't tried it on SuSE. Although I do have a OpenSuSE VM I use. It's just straight static (normal?) filesystems.
No LVM or BRTFS. But I like SuSE. We run SLES on a few servers here, those do have LVM and hardware RAID.
I don't know what kind of CPU you have, or how much RAM. But from my point of view...
4.7% and 2.1% aren't that bad. Less than 7% of your total CPU.
Your memory (RAM) might be slightly more of an issue.
20.4% and 10.4% are over 30% of your RAM. But still nothing to worry about really.
You will have to su - to root.
Then edit the /lib/systemd/system/plymouth-start.service file
With pluma, nano, or vi. (whatever you're comfortable with)
Change the second to the last line from...
save the file. Reboot.
Depends on what you mean by "see".
I'm assuming you want to copy files between them. Technically the answer is no.
Apple wants to own all your files. They can only go into the apple cloud. You aren't "allowed" to copy
them to anything local. (My biggest complaint against Apple). However...
