You need more room on your computer for the storage of iOS 12. You need more storage, up to 2 GB extra, instead of 8 GB to 11 GB for the operating system, for iOS 12. It means that for the operating system only you need 10 GB to 12 GB now. This relies on the type and generation of the device. This includes the pre-installed applications.
Those pre-installed 4 GB storage applications take over iOS 12. However, after installation, you can remove these. Read everything about this in our article on the removal of conventional applications.
If you have a 16 GB storage device, of which the operating system requires about 10 GB, there is little room left to use your own applications, music, and films. Perhaps it’s time for a new iPhone-although expanding your iCloud storage is likely cheaper.
iOS 12 also has system administrator constraints
If you are a system administrator in a business that uses iPhones and iPads, the arrival of iOS 12 and MacOS Mojave must also be dealt with. Apple announces some changes in a support document that won’t be good for everyone. It can lead to difficulties. Symantec certificates will no longer be considered as trusted as of autumn 2018. Also, Proxy Automatic Configuration (PAC) FTP and URL schedules are no longer endorsed. You can only use HTTP and HTTPS as the PAC URL after installing iOS 12.
The desktop also has some constraints. For example, the Kickstart command (more info) can only be fully used if permission has been given in advance for screen division. To enhance safety, this has been achieved.
Other constraints and safety characteristics in Mojave’s macOS may also cause issues with developers, for instance. Dave Nanian, the developer of the SuperDuper backup software! Criticism that you must grant approval for every little thing in Mojave. This is reminiscent of Windows Vista, where for every little thing you also had to agree with. Apple even produced a business video about it: it is completely stopped by Call Recorder developer for FaceTime. Development center ecamm will no longer update the software because in macOS Mojave it has become too complex.
