Hi, I've been using Microsoft software for the last 15 years and have lately started thinking about switching to the Mac platform (OS X). For the past few weeks I've been reading various Mac articles and newsgroups to educate myself. I have learned a lot, but still have a ton of questions. I would really appreciate anyone to please provide feedback (both positive and negative) for my questions below. I would especially like to hear from those that switched from Windows to OS X. 1. Does installing/uninstalling of new applications slow down the system? It seems that I spend ton of time just keeping my Windows running smoothly. After some time, the registry gets filled up with junk, and I have various background processes slowing my machine. I usually end up reinstalling windows every year to get rid of the junk I no longer need. I hardly have any spyware or viruses, but do frequently install software trials. I'm technical/geek enough to fix things, but I simply no longer feel like spending my time doing it. I want to use my computer without constantly fixing/tweaking something. Things get especially ugly when my 10 year old niece and nephew get on the internet to play Disney games - it doesn't matter how many firewalls, spam protections I have installed, they are always able to bring my computer to its knees. How is your experience with OS-X? Will I have performance problems after installing/uninstalling numerous software trials? Can I keep the system running smoothly without hunting which specific process is slowing down my Mac and cleaning up the system? How is your Mac performing after your kids played games online for a week? 2. Connecting to Windows network share? I have a media/backup windows server on my home network. It's not in a Windows domain, it's only in my Workgroup and is used as a file share server. Is it easy to setup a connection from the Mac to this file server to manage files, e.g. view/update photos, videos, documents. On my windows machines, I have a mapped network drive pointing to the central server - is there an equivalent on the Mac. I would like a solution that could remember the servers login/password, so that I don't have to authenticate every time I'm trying to get to a file? 3. Can iPhoto and iTunes manage media on a Windows network file share? 4. Is there a photo management/browser application that can match the speed of ACDSee for Windows? I do a lot of photography and use ACDSee as my photo browser application. I use Photoshop and Lightroom to edit, but ACDSee for viewing. ACDSee is extremely fast. I have a library of 20,000 pictures and ACDSee can display thumbnails extremely fast - I can scroll down a list of a thousand photos and it smoothly scrolls down without any rendering slow downs. I tried Lightroom, but it was extremely slow for browsing my library - I use it only for editing. I plan to use my Lightroom on Mac for editing, but don't know what app can give me the speed of ACDSee for image browsing. I've read numerous stories about how iPhoto slows down significantly with large photo libraries. 5. Managing multimedia on multiple HDDs. I may get some of the names incorrect on this one, so please bear with me. In OS-X, when I double click the HDD icon (in top right corner) it opens a file browsing application that shows links such as "Pictures", "Movies", "Documents", etc. in the left pane and when I click "Movies" it displays list of my movies on the right. I like this setup, but what happens if I have multiple HDDs and media split between multiple HDDs. Would clicking the "Movies" button display all movies on all HDD? If not, what would you suggest to manage large library of movies/pictures spread across several HDDs? 6. Is there a 2-button mouse? This may sound stupid, but is there such a thing as a 2-button mouse for Mac? I think, I've read that I can use a third party mouse (Logitech, etc.), but is there an Apple manufactured 2-button mouse? Windows users use the right button a lot for context menus, do Mac apps not use context menus? Thank you.
