Hello everyone, I am a new Mac user.

Recently I bought an iBook from a friend. Whenever I download a .dmg file, "Disk Copy" opens and I get an error stating, Unable to verify "filename.dmg".

I am currently running version 10.0.4 of Mac OS X and am trying to download an update, safari, and windows messenger. They all receive the same error. Is there any way around this?

Thanks.

I am truly very sorry to tell you this, but you need to get a more recent version of Mac OS X. 10.0.x was not a good version, and was only used by early adopters, nearly all of whom upgraded to 10.1.x as soon as it came out. No one uses it anymore.

As a consequence, no developers bother to test their apps against 10.0.x, and many of us use API's that were introduced in later versions, so you are very likely to find that a lot of software requires 10.1.x or higher (or, quite often these days, 10.2.x or higher).

I am almost positive that Safari will not work in 10.0.x.

I am unsure about your .dmg problem, but it is possible that the dmg format could have changed in one of the later versions - I don't remember. If it's not that, then it's probably a corrupted installation of OS X. In either case, your best bet is to upgrade.

Mac OS X 10.3.1 is the latest version. It costs $129 retail. If you are a student or a teacher, it is $69. This may seem expensive, but trust me, it is worth it. In addition to being compatible with a lot more software, 10.3 is much faster than 10.0 - there really is no comparison. The interface is also ridiculously better - it is so much more pleasant to use than 10.0 that once you make the upgrade, you will not be able to imagine using 10.0.

Run, don't walk, and upgrade to 10.3.

Sorry to be so brash, but this is just the naked truth. Ask anyone else around here, and you'll get the same response.

Ticking sound coming from a .pkg package? Don't let the .bom go off! Inspect it first with Pacifist. Macworld - five mice!

I tried downloading an update for OS X, but it wont even open the DMG. I am in major debt right now and cannot afford to buy a new version. I guess I am stuck, all I ever have is problems with Apple.

I have a brand new G5 running 10.3.1 and I have the same dmg mount failure issues.

Persistently gives Warning dialogue with this:

filename.dmg error -536870208

I have tried numerous workarounds, including one that suggeted that reinstalling 10.3.1 update fixes this problem. This did not fix the problem.

Anyone??

I found a fix with the help of weeding through a bunch of suggestions from the Apple Support Dicussions.

1) Remove the old 10.3.1 receipt from /Library/Receipts

2) Download the 10.3.1 standalone installer on a different machine. Mount the dmg there and then put it on a cd or something and transfer it to the problem computer.

3) Install the 10.3.1 update again.

This is a really serious problem on brand new, right out of the box Macs. SHAME on Apple for having such a serious problem on new machines....nothing like impressing those switchers
