This same week we installed the macOS Mojave beta one on Mac millions of users and the complaints about the compatibility of the applications or the possible problems with the tools that we use every day to work are minimal.
Obviously we are facing a beta version and this facilitates the possibility that an app fails in its operation, but as a general rule and without the need for developers to optimize the tools for the new operating system, the vast majority work well.
Do you mean that we can install the beta in all cases?
Well, this question is tricky and it is that personally apart from having the beta installed on an external disk so that it does not affect my work, what we have to think is that it can fail at the most opportune moment and leave us stranded, so surely we will not have problems, being cautious. The new version of macOS Mojave does not add too many changes in terms of the operation of the system, rather the opposite, it is an updated version of macOS High Sierra in which problems are corrected and overall system security is improved.
If you depend on the Mac for work, it is best to install it on a partition or an external pendrive to avoid problems, if you want you can install the beta version as an operating system but be aware that some apps may fail you. Just yesterday while we made the weekly Apple podcast with our colleagues from Actualidad iPhone, we suffered the consequences of updating without regard and the Hangouts app for Mac that we used to make the podcast live, the plugin for the live broadcast was failing a lot or rather (with sound errors).
In any case, we will soon have the public betas available and in them there is more "security" in terms of apps, logically it may be incompatible with an application or tool just like the beta version for developers, but in that case they are usually more stable . Best of all, we have really stable beta versions and few bugs or problems will give us, Do you have macOS Mojave beta installed? Have you had problems with an app?
