Because I am enrolled in the public beta program that Apple introduced with MavericksSince then I have been testing the different beta versions of both Mavericks and Yosemite before they were published as final versions. Now after a while I have decided to unsubscribe or at least the beta version updates in the app store do not skip since I need all the disk space for other tasks and I cannot be doing backups in the event of failures to reinstall the whole system in this case.
It is for this reason that I decided to unsubscribe when yesterday I skipped the update to OS X Yosemite 10.10.1 beta, but what is my surprise to see that could not carry out said discharge Due to a Spanish translation problem in the system, that is, when trying to click on the specific button in the preferences panel, I could not do it because it was not displayed due to the aforementioned translation problem that I will explain.
According to the Apple page, to unsubscribe and not receive new notifications, it would be enough to open the preferences panel, go to the App Store icon and click on the button. change your preferences for beta notifications. However, as I have already mentioned, due to an error in the Spanish translation, the button is not shown making it impossible to carry out said cancellation.
To do this, we must first go to «Language and Region» to change the system language leaving it in English, restart the computer and repeat the operation again so that it effectively lets us make the change and later return it to Spanish.
This is really a small inconvenience to carry out an operation as simple as the one shown, even so we can only consider it as a small bug that I hope they will correct for later versions.
