Michael Tsai, the developer of EagleFiler and the SpamSieve plug-in for Apple Mail on Mac, has written acaution macOS customers about attainable knowledge loss in Mail when upgrading to 10.15.0 (construct 19A583).
According to Tsai, he is heard from a number of customers that updating Mail’s knowledge retailer from Mojave to Catalina now and again says that it has succeeded, when in truth on nearer inspection it seems that giant numbers of messages are incomplete or lacking solely.
In addition, customers have reported the lack of message content material when shifting emails between mailboxes. From Tsai’s submit:
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 was once moved to a server mailbox, different gadgets see the message as deleted. And sooner or later this syncs again to the primary Mac, the place the message disappears as smartly.
Tsai warns that those problems are in particular pernicious as a result of customers would possibly not understand the rest’s unsuitable until they take 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 gadgets, and depending on backups is hard as a result of Mail knowledge is constantly converting and there is not any simple solution to merge restored knowledge with messages won because the final backup.
Despite the latter possibility, it is nonetheless excellent apply to make backups, however Tsai notes that Apple Support seems to be erroneously advising customers that misplaced Mail knowledge in Catalina cannot be recovered from a Time Machine backup made the use of.
According to Tsai, this isn’t the case: Apple Mail’s File -> Import Mailboxes… menu bar choice can be utilized to selectively import them into Mail in Catalina as new native mailboxes.
Tsai says he is not sure whether or not those problems are because of Mail insects or to different elements akin to issues at the Mac or with the mail server. Apple launched macOS Catalina 10.15.1 beta to builders on Friday, however it is nonetheless unclear if this model resolves the Mail app insects. Regardless, Tsai’s recommendation to customers who depend on Apple Mail is to “dangle off on updating to Catalina for now.”
