No, iostat gets it's information from the OS, not from the hardware. You could use smartctl - see this answer

There are two distinct questions here: Could you upgrade to 256G or 500GB Should you upgrade to 256GB or 500GB Let's tackle this backwards and start with the question that precariously walks the line of being an opinion and out of scope.... Should you? I'm going to take the official stance and say no. BTW neither Apple or Salers told me whether it is ...

Just solved the issue by updating Pages to the newest version! Thaks and excuse to everybody.

You can't install via the (alternate) and (better) restore method if your Mac doesn't have APFS-supported firmware. It's right there in the link notes. Then your recovery gives you the original you shipped with (in my case, Mavericks), and there is no way between here and the moon you can get a boot rom update to work if you don't have an internal SSD. I'...

I ended up verifying this scenario myself, you can restore a Time Machine backup from an SSD partition, onto another APFS partition that's on the same SSD drive You need to enable booting from external drives on T2 Macbook's, but it's a simple step that you are guided into (Everything available on MacOS Recovery with CMD+R) (You need the root password of the ...

It shouldn't affect anything, at least in the short term, as that's all I've had it disabled for. I had to disable it because on this MacBook Air (2011) it was using 50% cpu and causing the machine to freeze up.

At best, Time Machine will preserve the "sparseness" of the "sparse disk image containing a bootable installer" (saving space). Otherwise, Time Machine will "fill out" the backup to the maximum size of the sparse file. Which Time Machine does may depend on whether the backup is local or remote (and possibly other factors). In ...

I would absolutely encourage you to stop and make a Time Machine backup. There’s no harm in trying to manually twiddle things, but wouldn’t it be better to make your first backup in 150 days to an actual drive that’s connected? You won’t run into issues with installers being downloaded - those are just are large files that get saved one time and then don’t ...

I would load the app DriveDX which specifically looks for the SMART status of the drives. The app is not free but has a free trial period. You can use that to check your drive. It will tell you the SMART status and details about the drive. It very simple to use. Just start the app and it will start scanning your drives. Give it a minute or so to complete and ...

I would install Homebrew (brew.sh) if you don't have it already. Then install smartmontools which provides a heck of a lot more data. This will provide far more detailed insight into the health of your disk. Read about it https://www.smartmontools.org brew install smartmontools smartctl -a disk0 You can diskutil -list to get the drive id. smartctl 7.1 2019-...

The built-in 120GB is part of the Fusion drive. A Fusion drive is a software solution where two physical disks are joined as one drive. If either disk fails you can lose all data. Sounds like your 3TB HDD experienced a fault which is not unusual after 6 years of life. The 120GB SSD is soldered to the system board so that cannot be replaced It is ...

Your guess is correct. The 2017 model Macs can only EFI boot Windows. Since the first partition on the external drive starts at sector 2, the drive does not have the space to convert from a MBR partition table scheme to a GUID partition table (GPT) scheme. This means you would need to restart the installation process. When installing Windows 10, I would ...

Format your SSD as APFS and use it as your boot drive. That will make a noticeable speed improvement over using a magnetic disk. APFS is optimized for SSDs and runs poorly on spinning platters, so format your 120GB drive as HFS+. Your 120 GB drive is nearly worthless at this point. Maybe you could use a tool like Carbon Copy Cloner to keeps some important ...

Seems that MacOS has an option to do exactly what I need: sudo defaults write /Library/Preferences/SystemConfiguration/autodiskmount AutomountDisksWithoutUserLogin -bool YES Afterwards my external SSD is directly accessible by the daemon (if I wait some seconds because the daemon starts before the external SSD has been mounted). Additionally the external SSD ...
