Macbook Pro (Mid 2012) Startup Time Increased

Hi everyone,

I have a Macbook Pro (Mid 2012) non-retina model. I have an upgraded SSD (Crucial MX100). The startup time from switching on to the login screen is usually around five seconds but since this morning the time has increased to around 40 seconds. When the power button is pressed, the tone sounds and the screen lights up but it takes quite a while for the apple logo to appear. I haven't added or removed anything or changed any settings since before this happened. There doesn't seem to be any changes to the performance of the computer once it has started up, or the time taken from the password entered for the bar to load (Yosemite).

My hard drive cable once broke and I had it replaced at an Apple store (if that means anything to anyone). If anyone could give me any possible explanations or advise on how I can return the boot up time to the normal time.

Thanks,

Ben 🙂
