guys, just want to get your opinion on this. my company will soon be reinstalling fresh leopard os from scratch since they said that the upgrade have some problem. below is a transcript of the mail. is this really so based on your experience? """""""""""""" Dear All, Received word from Apple that upgraded versions of OS X Leopard are infested with many bugs which disable normal operations such as printing, surfing, uncontrollable hanging of applications or shut down....missing files, etc We are recently observing such happenings in our office. Preservation of our data is in order and to ensure uninterrupted operations in the near future. The only known solutions is to back up our data and do a clean installation of OS X Leopard. As this is a time consuming exercise, we need the co-operation and co-ordination of every staff to ensure that we can complete the exercise expeditiously. All staff must back up their data before Saturday 23 Feb. you can do this using the time machine program in Leopard into a USB or firewire drive. DO NOT backup programs as we will install this fresh over. Please collect your own LICENCE software such as MS Office, etc from Oliver which have the designated allotment of software in our office. Please also collate OS X Leopard installation disc if you see one to ensure as many machines can be setup as possible. PLEASE DO NOT USE THE OS X LEOPARD UPGRADE DISC. """"""""""""
