Mac software quick-fire questions
What is CUH? It’s slowing my Mac?
CUH is a process which can appear in Activity
Monitor taking up excess CPU, and is part of CorelDRAW for Mac.
If that’s installed and you’re having problems, contact Corel support. If you’ve removed the app, it may need separate uninstallation, try searching for it and manually removing it.
Why has my new anti-virus disabled Maps?
Maps relies on the internet for its data.
If the anti-virus software is blocking that, Maps will either look blank, or contain limited info. If you want to carry on using that protection, read its documentation carefully, but you’d probably be better off using a different product.
Better image editors like Affinity Photo let you compare two or more photos side by side and integrate well with the Photos app.
