My MBP had a hdd problem that I solved but then the HDD died and the new hdd inherited some problems via time machine: running slow now

I am using CleanMyMac2

The problems came BEFORE I started using cleanmymac ... I started using the software when I thought it might be clutter and yes, it seemed to be all clutter. However, a huge proportion of the 90 Gb was language files ... no idea what or where they came from but they are there every time.

Thanks Tony,

I bought the macbook determined that I would never fiddle with it. I have been using windows since 3.1 so have had to learn all sorts of things to keep the wretched things going.

If I click CMD+R, will the MBP just know what to do and just do it? Will I need to back up anything ... other than on time machine?

In other words, is it inuitive and relatively risk free!

See my replies to Tony T1 Bee.

now 91 Gb not Mb.

I am reinstalling as I type. Hope it goes well. I will report back.

I have reinstalled OS X now and will monitor progress.

Thanks Bee and Tony T1 for you help and guidance.

Hello Bee and everyone!

Everything went well as far as the process was concerned. I had no difficulty with any of it. However, the same old rainbow wheel of death kept appearing, the system was still running slowly at times.

I discussed this kind of thing with a friend a while ago, he's a computer/wifi systems geek. He suggested installing a smallish (240 Gb) SSD in place of my 1 Tb HDD, running everything off that and having all of my working, documents, pictures etc on my backup drives ... I am doing that now.

I formatted the SSD, downloaded OS X Mt Lion and am currently upgrading to Mavericks.

I am using my time machine to bring back my data etc files and I will reinstall my software package by package.

I think it might be overkill as I did think that I could take my 1Tb HDD right back to the start and do the same.

Anyway, later today I will have Mavericks back, Office back, Adobe software back ... and I should be running at a good speed!!

That's a fair point and it IS one of the things my friend told me to do. I take the blame for everything I have done, however!

I've got the SSD running and settling in and I have to say Photoshop CC opened at a blistering pace. I mean 5 seconds v 50 seconds.

Why haven't I bought the memory yet? I live in rural Thailand and getting such memory is difficult with reliability. So, I wait until I travel for work, often to Kuala Lumpur. I bought the SSD there over the weekend. My track record with RAM there is iffy. I bought 2 Gb last year for my HP laptop and within a month it had failed. I bought replacement memory for the same machine earlier this year and that might have caused me problems, I think, as the video card crashed shortly afterwards. All repaired and working well now, including that latest memory. Maybe not a memory problem that time.

So, I am keen to wait until I can get some 100% copper bottomed reliable RAM for the Mac.

The performance has improved as I just demonstrated and I am sure I will find the same when I set to work on a large Word or Excel file.

In the meantime, the machine is still running hot, due to the low RAM I suppose!

Thanks again for your interesting as it is very useful for me to see these views and I am happy to explain my what and why!
