Hi fellow devs, recently i got to the point where i think about porting my current project to the Mac after having successful tests on Windows, Ubuntu and Android. The plan is to get a used model, the one i intend to buy has MacOS 10.9.5. What i do not know, which hidden costs there are. An update to 10.13 and Xcode will be needed - it seems they can be downloaded from the Macstore, but you can only access it with a Mac. Can anyone provide information as to how much the update and the coding tools cost ? Sorry for the ignorant question but i couldn't find anything up-to-date regarding this.
