Speed of loading of Mac version of PAYE Tools

Can anyone tell me why the Mac version of PAYE Tools takes the best part of a minute to load. This is ridiculous and has been like this for as long as I can remember (at least 8 years). I raised this self same issue at least 4 years ago and was fobbed off by saying it takes all that time to load the data file. I have 3 employees and a data file size of 7MB. I can load the Apple Photos app on my Mac (which has a file size of 100GB and contains 25,000 items) in less than 2 seconds. I was also told previously that it must be a poor internet connection which is a complete red herring as the app will load with the internet connection switched off. It has to be poor programming, there must be timeouts that are set for some reason and the software waits for them to expire. I can't understand why the programming team is not utterly embarrassed by their work.

Hi,

Basic PAYE Tools runs many complex tasks in order to fully load the application’s functionality. HMRC are aware of the impacts to load up time and are always looking to better the application launch performance with each new release.

Thank you.

But it is not half as complex as many applications that load in the blink of an eye. I just don't accept that explanation, it has to be some artificial timeouts built into the software. PAYE Tools is unique amongst Mac software in its incredibly long load time, at least 10 times as long as anything else.
