If you use sqldeveloper on windows 10 on mac parallel VM maybe you have the next issue: a very small fonts and GUI interface (Actually it's so hard to read every word )
The solution for that issue is change the properties for sqldeveloper.exe file:
On the next window on the compatibility tab, you need to select the option button "Change high DPI Seetings"
Here you need to change option High DPI Scaling override to value : SYSTEM
And after the change you'll have your sqldeveloper with very normal font size and GUI :D
Cheers
