Terrible UI and unreasonable price. Perhaps if they rolled all their packages together into one multi-function program they might get some sales. I wouldn't spend $50 on a program that only did one job!

This program is bilge-water of the foulest degree. Not only does it bring your Mac's performance to unusable levels, it convinces you that the performance drop is due to problems with your Mac preceding the installation of MacKeeper. I have worked with macs for 12 years and this is without doubt the worst collection of "utilities" since Norton didn't survive the transition to OS X.

I received this call from my client today "Hi, my Mac's been running slow for three weeks now, MacKeeper tells me that there are hundreds of junk files being created every minute, do you think i have a virus?"

My reply "Yes you have a virus, it's called MacKeeper, drag it to the trash and remove it. it's Eastern European scamware that convinces you your Mac's running slow and needs fixing when it doesn't."

Two hours later my client called again "Thanks for your suggestion, my Mac is once again back to normal speed".

To the developers, perhaps devote some of your marketing budget away from advert spamming and paying for fake reviews on MacUpdate by accounts that only ever make one review then disappear, why not hire ethical developers who can write decent software to actually help people instead of extorting money from the less well-informed.

By Keiki you mean Yoshi of course, and by Carry On Farming, you of course mean Yoshi's Island, or are you ripping off the British Carry On series filmed between 1958 and 1978?

I think even you are confused as to where you got your ideas.

Given that this requires a purchase of FileMaker Pro and setup of a MySQL server, what advantages does this have over a free product like Google Calendars or iCloud, which currently work cross-platform?

On the PC you can view a google calendar via the web interface, or use Google Calendar Sync to sync your outlook calendar with google.

On the Mac there's iCal or the web interface.

How can a FileMaker calendar stand up to this?

You'll love this program if you like any of the following :

Expensive programs with very few features to back up the price tag
Interface design from the 90s inspired by KidPix
Jaw-droppingly slow and buggy software

if you have $30 to waste then jump right in
