QGIS is performing very slowly for me when browsing files and folders recently. I am running macOS Mojave and have no performance issues within QGIS, apart from the times I need to open or save a file.
I'm running the latest QGIS (3.4.4) as of 29/01/2019
I thought this issue may have been related, but the slowness of the finder window applies no matter which folders I am navigating between.
I have tried uninstalling all the plugins I have one by one, but that did not resolve the issue. It is making it very frustrating to use QGIS because I need to wait every time I save a file.
Again, this is a recent issue and I have not yet worked out what changed that may have caused it.
