SHRALLDAM  Very satisfied by this application. The original Palm Desktop software doesn't work very well on my Mac Pro (and it's not Universal, btw). I've bought the Missing Sync and I have no regrets : reliable, easy and elegant.

DRUMMERBOY5678  This is great but you have to pay $40 dollars for it. I found out a way of doing what it does for free! I made instructions at:

(Version 6.0.4)

BIGDAVE56  This app still needs serious work IMO. Failed to recognize synced calendars from previous versions. Went into conduit settings and selected the calendars I wanted. Events still don't show up in iCal. Told me user profile could not be synced because of conduits not existing and that I should edit profile. When I clicked 'OK', profile selection cleared, making it impossible to edit profile (and no information as to what needed to be edited was provided anyway.) Setup Assistant failed to recognize or rectify either of these problems. Sync was dramatically slower than v5.x under Tiger, especially considering all the information it failed to sync. Think upgrade is overpriced also, frankly. A major disappointment. This is as a longtime user of versions 4 and 5.

BSEIDNER  I had 15 years of Palm Desktop Windows data that I needed to move from my Treo 755p to iCal.

I had been dissatisfied with the Hotsync/iSync duo and decided to try Missing Sync despite the mixed reviews.

My first try was a disaster of over 9,000 conflicts needing reconciling.

I ponied up the $$ for a consult from Mark/Space and a very competent and thorough support fellow took control of my MacBook remotely and fixed it right up.

This program has worked flawlessly on my Tiger MacBook for a month.

The included conduits and applications are more than worth the cost of the program. It syncs all video and pictures I shoot. It syncs selected iTunes. There is a great app that mounts the Treo memory card in the Finder for file transfers. The Notepad is very capable and I use it instead of ToDo.

I am very very satisfied with this product. In the real world sometimes things don't work magically out of the box. This did not but it was dealing with a ton of data that had traveled across multiple platforms and operating systems. It took only a paid support call to straighten it out because I lacked the expertise. The whining about this product has me shaking my head.

It has been rock solid and better than that, it has been invisible

DARRELLMAC  Missing Sync has worked well for me over the past three years. I have consistently been able to sync my Treo 650 or Treo 680 to my Mac with very few problems, and when I had problems, they were nearly always a result of conflicts I had created with changes to the programs on my Palm or the categories into which I divided my data.

Moving to Leopard created some challenges. I was one of the lucky people who found that 6.0.2, beta 2, released within days of Leopard's release, worked flawlessly for synchronizing my iCal and Address book which are my only critical daily syncs. From reading the Missing Sync Beta Forums, it was clear that many folks were not so fortunate. In such cases, where problems are not consistent, it is very difficult to know whether the problem originates with Apple OS X, other third-party applications, or Markspace, the developer of Missing Sync.

Nonetheless, Markspace made betas available throughout the development process, provided forums for public comment (and comments gathered in such forums ALWAYS run to the negative, since people are far more inclined to voice problems,) and appeared to me to address the radical changes in Leopard rather quickly, given that many of the changes to the way OS X syncs were very late changes in the development of 10.5.

The final version of Missing Sync for Palm 6.0.2 works very well for me. I followed Markspace's release notes' directions of backing up data and overwriting data on my Palm with data from my Mac on first sync.

I post this review so other readers will see there are people who have come through the transition to Leopard and Missing Sync for Palm 6.0.2 quite satisfied. I do not intend to suggest that problems others have had are not legitimate. Missing Sync works great for me and I will continue to use it until iPhone 2 or 3 hits the market and makes its use unnecessary.

PCOHEN961  Do I hear a Class Action Suit. Do you think this thing will EVER work. Doubtfull.

JAN13  I have this software for long time. Always in a hope, that new upgrade for which I do pay heavy $$$ will bring stability and most importantly functionality !!! I hear you laughing all the way up to here ... like if I am naive or so ... Well, my friend I was naive NOT anymore since I am NOT willing to spend for this trash software a penny !!! I am now on OS 10.5 and of-course, Missing Sync for Palm OS 6.0.1. does not work ... well good news is, that old five hundred years old original software HotSync manager from Palm does work, and work perfect !!! Aaaaach .......... Good Old Palm !!!

EYKANAL  I bought missing sync for the purpose of being able to utilize Categories in the various applications (Palm Desktop didn't support this). I found that it was a fairly good program. It was able to correctly sync my contacts using address book (not some proprietary program, as Palm desktop does) and my calendar and tasks using iCal (again, not using some proprietary program). Mac does not have a default Notes program (more on that later), and unfortunately the proprietary program included is terrible. You can only view your notes but not edit them, and the resolution is very poor. I had few problems syncing my Palm Z22 with my Mac, but there were a few occasions when my palm began duplicating calendar entries each time I synced, causing there to eventually be ten of each entry. After speaking with the company I was able to find a temporary work-around, but the problem did recur.

The one-star rating is due to the reaction of Mark/Space to the release of Leopard, Mac OS 10.5. Upon release, Mark/Space notified their users that the current program is incompatible, and a fix will be available in **3 months**. Their product is advertised on the apple.com website, and is THE main sync program available for mac users. Rather than purchasing a developer machine and writing the new version before the release, they apparently waited until general release to begin testing. What's more, they released this version (v. 6) just a few months ago, when it was public knowledge that Leopard was going to be released in just a few months. Such an abandonment of their user base leads me to suspect the ethos of the company, and definitely has me searching for alternatives to their product.

All in all, they have a fairly decent product, but their disgraceful abandonment of the Macintosh community during 10.5 release leaves me with a very sour taste in my mouth for them. I am currently seeking an alternative sync solution.

SINZOO  i upgrade to v.6.0.1

it really bad, not worth a penny

1. worse user interface than previous version (the design is so 2 minutes ago)

2. new sms log can't be sorted by time, name or any other ways. it's useless.

3. notebook can't bring my memopad data to it. if it can't, why create a new app? and i can't use my memopad anymore....
