Questions and Answers
1. Preview has a memory leak when dealing with PDF files. Recently I had to do a lot of work with PDF, and lost 40 GB of disk space. How do I recover this space.
We think it should be a cache file management problem. Also Preview may be saving versions of files, but that should be visible. Maybe virtual memory files are eating disk space. Perhaps a disk optimization program might find the missing space. Use the console to check for recurring errors. Perhaps the logs are increasing without limit.
2. Booting up MacBook Pro, it seems to always use a WiFi connection rather than an ethernet connection, even though the ethernet is plugged in and ready.
In Mac System Preferences -> Network Settings, you can enable several different connections simultaneously. The priority by which each will be used is set by the order in the list of connections in the network settings control panel. If you wish ethernet to have the highest priority, simply drag the ethernet item to the top of the list.
By the way, the same is true for setting the priority of WiFi connections, should more than one WiFi “hotspot” be available in a given environment. Simply drag the item for the most preferred hotspot to the top of the list that is found under Network -> Advanced settings.
