So if you want to have one, now is the time to put it in place. There are two good ways I can think of to do this:.source url
High Sierra APFS Raid 0 Set-Up - Help!
In either case, when we're done, we should end up with something like this if we run diskutil list at the command line:. So in addition to a Recovery partition, we also have an OS installed. If you did a manual install of the OS, do not go through any of the Setup Assistant steps that are presented on a fresh install at least, not quite yet. This part actually tripped me up in an unexpected way.
I had a clean OS installed, so I opted to restore from Time Machine when prompted by Setup Assistant — well, I would have if I had the necessary passwords in front of me. My wife's computer also connected to this same Time Capsule, so I was able to retrieve the password from her Keychain to connect to the device, but I could not come up with the password to access my machine's backup.
Of course, this information is in my own Keychain and, in my case, in a database as well , but since I have no access to my data right now, I need to go to Plan B. Plan B was to take the disk image I created of all my data and clone it to the Fusion Drive.
Unfortunately, when I tried to do that, Disk Utility claimed that there was a size mismatch and that the contents of the disk image could not be copied.
Use Disk Utility to Create a RAID 0 (Striped) Array
Regardless if you took my circuitous route to get to this point or not, you are now ready to restore your data. Here's I followed through with Plan C:. If you, however, have access to your Time Machine backup, you can choose to restore from there. If you have a valid macOS Recovery partition, that's probably easiest, as the Restore from Time Machine Backup is the first choice in the menu; just start it off and follow the steps. Alternately, if you chose to install an OS on your Fusion Drive in Step 5, you could boot from that and proceed through Setup Assistant to the point where it asks if you want to restore from Time Machine.
As a final alternative — which is most useful if you were living dangerously and decided you should upgrade your OS to a new major version at the same time e. You would think it would be trivial to get that up and working — and the hardware part was — but Disk Utility held fastidiously to the belief that this drive was part of a RAID and it would not let me divorce it from said configuration no matter what I tried. So it became necessary to repurpose it using the command line. Here are the steps:. Optional: A current macOS Installer e.
Step 3: Perform Mac mini Surgery Swapping in the new SSD for the old hard drive is slightly tricky, but I found it to be manageable — and this is from someone who is more software-oriented than hardware-oriented. So based on the information from diskutil list above , I used this command to create the new Fusion drive: sudo diskutil cs create Fusion1TB disk0 disk1 Note: cs stands for CoreStorage; you may use the form diskutil coreStorage … if you prefer. Make certain the disk with the data you wish to restore is also connected and available.
The integrated graphics of the Macbook don't hinder performance quite so much as you might expect, compared to the Macbook Pro with its dedicated graphics hardware, but could be the reason the user interface becomes particularly sluggish when the system is running flat out.
On the whole, the Macbook is a pretty good portable system if you're on a budget though it's worth installing the full 2GB of RAM , and while you can't order the system with a rpm drive, it is at least possible to purchase this later and swap it with the supplied internal drive yourself.
With two drives, I could record 11 tracks while playing back 96, and the maximum number of tracks I could play back was With three drives it was possible to record six tracks with tracks playing back or record 12 tracks with playing , and the maximum number of playback tracks possible was While you do see a benefit in performance using a RAIDed volume, you'll notice that the increase is small.
You'd get better performance using the drives independently than together in a RAID configuration. I only tried up to three drives, because it's best to keep the system drive separate to the audio RAID, just in case of a drive failure.

As a comparison, I did a test in Pro Tools to see how many tracks I could record and play back simultaneously. With each track in a Session assigned to a different discrete input and output, I could record mono tracks on one drive simultaneously and play back As a footnote to these tests, I just want to make a couple of final observations: firstly, you'll notice that Logic was able to record and play back far more 'channels' of audio than Pro Tools from a single drive: Logic 's tracks were stereo, whereas Pro Tools ' tracks were mono.
Because of this, though, Logic was able to work with interleaved files, which Pro Tools can't do, and with an interleaved file Logic can continue to read the second channel without having to seek to a different location on the hard drive to find the next file. This situation helps to illustrate just how important drive seek times really are.
Secondly, these tests show theoretical maximums because the recording playback files on each track were contiguous regions without edits or crossfades. And, finally, while RAID systems don't provide a huge performance boost for audio work, don't forget that performance isn't the only advantage, and you might consider that recording to a RAID 1 system is a good thing just in terms of reliability.
Fission is a new audio editor that lets you work destructively with compressed audio files, without having to recompress them again resulting in a loss of quality when you save. Rogue Amoeba, known for their Audio Hijack application, which can record the audio output of an application into an audio file, released a new audio editor this month.
Fission 's name is relevant because it has the unique ability to make edits such as splitting up long recordings into separate, shorter files directly on compressed audio files such as MP3 and AAC without the user having to convert the audio into raw data and then re-encode the output again.

A test version is available from Rogue Amoeba's web site www. Apple Notes. I went from having a completely empty spare drive to having barely any space at all left on my iMac. The only thing to do once that happens is to dig through and manually delete files.
Your personal libraries are going to be the biggest Movies, iTunes, and Photos. Unless you have already started saving new data to the drive with High Sierra, you can go ahead and delete them from your new boot drive. Just make sure that, when you open the programs, you hold down the Option key and select the location of the original library. Otherwise, High Sierra will create a new, empty one for you. For that to happen, you have to break the set in Disk Utility.
