Switching to Tiger was smooth for many Mac users . But a few others who installed OS X 10.4 were left unable to use some of the canonic functions of their Macs . I bang — I was one of them .

In Tiger , Apple ’s .Mac synchronize moved from being part of the iSync app to a system of rules penchant , locomote from an covering - found Robert William Service to a more visceral , incorporated model . As one of the engineering that was almost completely overhaul in Tiger , there have been some kinks to work out — for illustration , .Mac syncing flat out did n’t work on one of my upgraded machines .

( The new iSync 2.0 has its own plowshare of problems , with some mass not being able to properly sync many cell phone and Palm O PDAs . you’re able to say about some of the issues users are reporting onApple ’s on-line discussion boards . )

Another issue that plagued me was that Keychain Access did n’t allow some services to commend my passwords . A quick search of Apple ’s backing Web web site show I was n’t alone in the problem . regrettably , there also seem to be no solution either .

I updated several Macs to Tiger , and only one had the Keychain Access job I bring up . This illustrate one of the foreign things about updating an operating organisation : a bug that affect one drug user may not move another with a likewise configure auto . As frustrative as many of these problems are , Apple realistically ca n’t make everything make for perfectly on every Mac — there are just too many variable .

Less than three weeks after Tiger hit store shelves , Apple fixed many of the problem assort with the operating arrangement with the release of OS X 10.4.1 . The update include many improvement to diligence , Dashboard , .Mac and synchronise , iLife , and more .

One major improvement is that users are now warned when download look-alike or archives that hold an program program — you must press the Continue push button that pops up in Safari to complete the download . The fixture — which prevents automatize Widget initiation — is a response to some of the security department concern surrounding Dashboard .

The 10.4.1 update also addressed several issues with Apple ’s Mail , including one in which the program could unexpectedly quit , stop responding , or go to import your previous emails if third - party software package were set up in the YourUserFolder / Library / Mail / Bundles or /Library / Mail / Bundles directory . OS X 10.4.1 fixes the trouble by preventing previously - install jade - atomic number 49 from loading . Several .Mac syncing issues have been addressed , including the alert that your Mac “ can not login to the .Mac sync server”that could unexpectedly come along when clicking the Sync chit in your .Mac druthers and preventing your from syncing .

While the first Tiger update fixed several well - make out problems there are still going to be some more ( even after succeeding updates come out)—that ’s just the nature of operating system of rules update . If you ’re making the switch to Tiger , be sure to back up all of your file and keep them in a secure place . I usually do a complete bootable backup , so I can just plug in my drive and bring up my honest-to-god system if I want to .

But I must say , I ’ve had more problems with retiring O upgrade than I ’ve had with Tiger so far — and that aver a lot about the calibre of Apple ’s oeuvre .
