DYLAN MCNAMEE  I sympathize with your frustration, but this comment sounds baiting (stuff like this makes me prefer Windows). For free software, ease of development is a big deal. With each version of MacOS, Apple makes leaps in making free software easier to write. Developers don't do this out of spite, unlike the tone of this comment.

DOM21  Forget Winbloze, I felt the same disappointment when I scrolled down, too (OSX 4.11).

LOKHEED  And Leopard has been out for nearly a year now. How long do you want to keep supporting stragglers? Should programs not take advantage of new Leopard functionality and features to keep those not wanting to upgrade happy? Upgrade or stick to using old software... can't have your cake and eat it too. It's not like Leopard has been out for a day and EVERYTHING now requires it. You haven't been left out in the cold in a matter of days like you like to play up...

Progress is called progress for a reason. Stick to using iAlertU. Last I checked, it supports Tiger just fine.

This flame bait has not place here.

SJJ_PUBLIC  While the original post was obviously a troll, there are many of us who have Macs which can not run 10.5. I have one such computer (PowerMac G4 Dual-533). Also, there are those of us who have a computer that can run 10.5, but have not updated yet. I have one such computer (iMac G4 1.0 GHz.) I have 10.5 on my MacBook at work, and while it is very nice, at home I'm not sure it's worth buying at full price. 10.4 still works great for me. I'd rather wait for 10.5 to become bargain basement priced once 10.6 is out. I use to be of the ilk that as soon as an OS update was released I bought it, but I'm no longer like that. In fact I was planning to skip 10.5 altogether and wait for 10.6, to save money and get a bigger upgrade versus 10.4, but now that 10.6 is no longer going to supporting PowerPC, I'm stuck with 10.5. Just not yet.

WHAT THE?  your comments make me snore!

AIKOUSHA  Stragglers? New functionality? Yup, I just love buying new hardware and software every six months and trashing thousand of dollars of hardware every year. Yup, I guess that's the whole reason for owning a computer...

I want the developer to know there is interest, but that it has to stay as only an "interest," unless it can work with "antiquated" 12 month old systems.

Sorry, but Leopard has removed nearly 5 times the functionality that it supposedly added, and Tiger did the same, but not as bad, even though it's upgrade prevents nearly $50,000 worth of professional equipment from working with the computer, that will never be upgraded itself... I'd call that waste, not progress. However, ALL the windoze software we have works from 95 all the way to XP without issue in any direction, and I find that sad.

I understand that upgrading is the neatest thing for some people and applications. But it isn't necessary for most of the things we end up testing, reviewing and using,, both here and for other places.

I use my Mac primarily for work, and all the Macs at work are used ONLY for work, however, 2 cannot be upgraded to Tiger because of loss of functionality, and the whole company cannot upgrade to Leopard for the same reason.

If admin feels this is a "troll," please feel free to remove it and the other comments, but the original intent was serious.

8BITWINTERMUTE  Lots of developers seem to be taking the path of least resistance and making little or no effort to make their stuff backward compatible. It's a shame, in a lot of cases there's barely any reason at all. I don't know if that's true for this one though. I've seen an application that generates white noise being 10.5 only - there's no excuse for that.
