I have problems with QuiteRSS for MacOS Sierra and High Sierra.
I have 24 sources with updates every 30 seconds and apart from that I do not receive updates every 30 seconds, but the popup almost never comes out. Then when I run from one source to another, it often freezes for 1-2 minutes and then returns to work. I rarely have to close it with Activity Monitor. With Windows 10 everything is perfect, no problem.
My iMac has these characteristics:
iMac Mid 2011
I7 2600 3.4GHz processor
Ram 4GB 1333MHz
SSD Samsung 840 EVO 256GB
How can I solve?
