Recommendation: Delay Upgrading to MacOS 10.15 (Catalina)

|

As with any major OS release, we recommend a cautious approach, especially where your primary device is concerned. Major releases often bring new issues or bugs, which may take some time for the vendor to address with patches and updates.

We have reports that Mac users who have upgraded to Catalina from a prior version of MacOS (or who have transferred data from a system using a prior version of MacOS) have experienced problems with wireless networking. In particular, users may see no wireless network SSIDs available, and users may be unable to connect to any captive portal wireless network (frequently used at public hotspots).
