There is something that has been bothering me something fierce since I made the switch to the Mac.
When I used Windows I could connect and disconnect USB drives whenever I wanted without fear of losing data. The way Windows works, it's designed for this so you don't have to "eject" the disk every time.
OS X however is different. I have a USB hub, which has at any given time at least 4 drives plugged into it. If I want to say, grab my laptop and head out the door, I have to wake it up, eject all the disks/media cards, and then go.
I find this to be extremely annoying, especially when I forget.
Is there a way to make OS X behave like Windows in this regard?

On a Mac OS X 10.4.11. laptop. ISP provider is Comcast. Have successfully been sending and receiving emails at home no problem using Entourage for two years. Have now taken laptop to visit away from home and clicked into the host's house wifi system - AT&T u-vers.
Entourage will now receive but not send emails. Receive 3259 error message about timing out. However, can send fine by going to Comcast's site, therefore Comcast insists this is not their problem but an Entourage problem, probably with settings.

I am trying to install Mac OS X Lion I just downloaded. At the step where it asks you to select a disk to install, I got this message:"This disk is not formatted as Mac OS Extended (Journaled). Use Disk Utility to enable journaling or reformat the disk."What does this mean? Please help me through the steps to complete my installation of this software.

Been months and issue is still the same, why does my desktop work blazing fast online from browsing to loading streaming videos etc. And my Macbook Pro can't, its a little slower browsing online which I can put up with but youtube, rottentomatoes, basically any streaming type site sucks. And it doesn't matter whether it's by wireless or connected directly by ethernet. It just buffers like every 15 seconds (does the samething on Safari and Chrome). I mean before my 4 year old HP laptop died it could load videos on those same sites almost instantly with no buffering.
I have a friend with an Imac that does the same thing, and a buddy brought over his MBP 15 and same thing happened like at his house, and I showed him how fast the desktop is in comparison.
I just moved to a new condo, have high speed internet from Comcast, and its def not the internet since the desktop works perfect. Any ideas on what to do as I use this MBP more being I carry it around the place and its so irritating knowing how quicker my desktop is, and that desktop is 2 years old.
I've tried different DNS etc and that helped a little bit (was a lot worse before) but still sucks, this is what I have inputted from this forum under DNS servers:
208.67.222.222
208.67.220.220
4.2.2.1
4.2.2.2
8.8.8.8
8.8.4.4

I got my Macbook Air connected to the internet, and want to connect my iPod Touch to the internet through my Macbook Air. I saw people using their Macbook Pro to share the wi-fi through their AirPort. How about Macbook Air? As I don't see such option in the Sharing preference, I downloaded the AirPort Utility and it simply says I cannot install it.

I'm on a boat in Fiji, using a Vodafone wireless dongle, and keep losing my connection. My vodafone software and my apple network software show I'm still connected, but suddenly I can't get into another page, or if I'm downloading a software update, I get a message that I have a timeout error. I then disconnect my connection and re-connect and then things start happening again. However, I have not been able to stay active long enough to download my apple software updates which is really frustrating. It seems to happen more often when I'm downloading something sizeable, like a video or software update, but happens other times as well. I'm a mac novice, (bought this, my first mac about 10 months ago) and not terribly computer savvy to begin with. Looking through this forum, I'm confused by much of what I read, but I'm beginning to think this problem may be beyond my capacity to solve.

My macbook pro has been acting weird for a week or so. I'll be on the internet and then it will randomly shut down safari or google chrome and send an error report message. This also just started happening with my iPhoto and iTunes as well. Sometimes my computer will just shut off completely and restart with a message saying there was a problem and it had to shut down. It seems like there is some bug or maybe a third party add on I need to get off?

A friend of mine is having an issue with the wifi. When they use a MacBook on a wifi network, it tends to keep the family's IBM laptop off the network. This happens on all networks the two computers try to join, and in some cases other PCs on the network.

I have the following:
Mac Book Air with 10.5.8
iMac with 10.6.4
Purchased 10.6 Mac Box Set
When I try to access and install 10.6 on my MacBook Air, I get the following error:
"The operation cannot be completed because the original item for "Mac OS X Install DVD" cannot be found"
I am trying to use remote disc on my iMac to access the 10.6 install disc. I used the the "Ask to use" option on my MacBook Air, and then selected "Ok" on my iMac to give permission. Despite this I get the above error.

I'm having issues setting up a Tri-boot system on my Macbook. I can't figure it out at all. I've created the partitions, and began installing XP. After the set up, the machine reboots to finish the install, but I get a 'disk error: press any key to reboot' error after the install. I am not installing though Bootcamp, and I have insured the drive is an NTFS drive, as that is reason the disk error usually appears.
