i'm plaining to reinstall mac osx. to make change in partition of disk. i'm linux user. so i usually separate / and /home on different partions. because it make it easy to backup datas with remaining /home untouched when installing linux just in cases. files in /home will be saved and not only original files but backuped files. unless diskfail happen, datas in that directory is permanent. and now i'm seeking workaround for mac. because mac osx become my first OS. and i'm making mac osx my main system. linux is second and windows for banking is third. for that reason, i've searched internet and read some articles. they said to make simlink to /User. but i found out that simlinked /User leads some applications unworkable. separating file systems is not recommended on mac? it's not supported? if so, how can i save files when reinstalling mac? just use external disks or back up files at web hard? it's inconvenience and not acceptable to me, i'm using dropbox a forum user recommended though... yea.. i know mac or linux based on unix is stable and not easily broken down. but i usually do something on OS very often. i make a plan for that. thanks for reading my thread.
