root | PSA: Apple Mail Bugs Can Lead to Data Loss in macOS Catalina

Michael Tsai, the developer of EagleFiler and the SpamSieve plug-in for Apple Mail on Mac, has written a weblog put up caution macOS customers about attainable information loss in Mail when upgrading to macOS Catalina 10.15.0 (construct 19A583).

According to Tsai, he is heard from a number of customers that updating Mail’s information retailer from Mojave to Catalina once in a while says that it has succeeded, when actually on nearer inspection it seems that enormous numbers of messages are incomplete or lacking completely.

In addition, customers have reported the lack of message content material when transferring emails between mailboxes. From Tsai’s put up:

Moving messages between mailboxes, each by the use of drag-and-drop and AppleScript, may end up in a clean message (most effective headers) at the Mac. If the message used to be moved to a server mailbox, different units see the message as deleted. And sooner or later this syncs again to the primary Mac, the place the message disappears as neatly.

Tsai warns that those problems are in particular pernicious as a result of customers would possibly not understand anything else’s mistaken except they have a look at affected messages or mailboxes. Since the information is synced to the server, those issues too can propagate to different computer systems and units, and depending on backups is hard as a result of Mail information is constantly converting and there is not any simple approach to merge restored information with messages won for the reason that ultimate backup.

Despite the latter chance, it is nonetheless excellent apply to make backups, however Tsai notes that Apple Support seems to be erroneously advising customers that misplaced Mail information in Catalina cannot be recovered from a Time Machine backup made the usage of macOS Mojave.

According to Tsai, this isn’t the case: Apple Mail’s File -> Import Mailboxes… menu bar possibility can be utilized to selectively import them into Mail in Catalina as new native mailboxes.

Tsai says he is undecided whether or not those problems are because of Mail insects or to different elements similar to issues at the Mac or with the mail server. Even so, his recommendation to customers who use Apple Mail is to “cling off on updating to Catalina for now.”
