Mbed Studio 1.2 on Mac OS 10.14.6 ARM compiler license problem

[ERROR] armclang: error: System clock tampering detected. License checkout will fail.

I am ashamed for Arm Mbed that this problem has not been solved nor I get any help on this, meanwhile for more than 9 months. It is just frustrating that I can’t work with Mbed Studio for no apparent reason.

PS: I own a Keil MDK License which I use from time to time on Windows, however the Mac is my main device.

Any help would be appreciated.
