Two different issues - Most likely connected
First Issue:
When my MacBook Pro is shut down, I start it up and the Apple symbol appears with a status bar line that slowly fills up. It then prompts me to the start-up window where I enter my password and am admitted into my computer. In the next minute a text box appears in the middle of the screen displaying the following message:
“/Library/StartupItems/HP USB EWS Gateway” has not been started because it does not have the proper security settings.
Every time I click the question mark, which opens up the internal Mac search it says that is has found no results. So I am forced to click OK because it hovers in front of every window I open.
Second Issue:
When my MacBook Pro is in sleep mode, lid closed, remained logged in, and I open it and 'wake it up' - the screen goes from black to a semi-opaque white where I can see my desktop photograph (barely). A status bar appears at the bottom made of about ten ovals which slowly, from left to right, become white. When they are all white (status bar complete) the screen becomes normal coloured and I can see my desktop photograph. The mouse remains frozen after a minute or two the mouse moves but I cannot click on anything and my dock will not pop up when the mouse runs over where it will bring it out of 'hiding'. After another couple of minutes of moving the mouse around and randomly tapping space or enter (which probably doesn't do anything) I can finally access things normally.
So:
I've tried looking this up and the only real straight forward answer I could find was to go into Desktop Utility, First Aid - I have Verified the disk, Verified the Disk Permissions, Repaired the Disk Permissions, and Repaired the disk - to which there were no problems, save for the re-grouping of some items which were all regrouped successfully - then I restarted the computer and was still met with the same results.
I'm not a tech wiz but if you can help fix this problem in a clear and simple way then I can save a trip from the country into the city; and a crazy packed Apple store in psychotic mall.
