Thank you all for all your help... clarification......
Currently, I use 2 machines one for home use which is an IMac mid 2010 I-7 intell, 2.93GHz w/ 12GB ram that I have opened up and replaced the HDD with a 1TB SSD and I am very happy with the results (which I should not use for work because it is not a secured cleared machine per company protocol). The other is a big box windows 10 model I-7 Intell that I have updated the ASUS MB (that is cleared for work where I had to physically bring in the unit so they could update items to company spec.) I use for work due to the issues that Apple would not share certain protocols needed which I have been informed has been worked out now.
Therefore, I now have to re-think it maybe it's time to re-consider what use I will have for the MAC Laptop. People that that I work with say if I am going to spend money on a MAC LP it would be better to obtain a unit that I could use for work as well as other functions and get a unit that will do it all. So, if I use the Mac Laptop for work that MAC will have to perform all the necessary operations as remote server log-ons and word processing plus many more complicated programs that the MBG4 may not be able to handle. So now the the situation has changed somewhat as to the use of the MAC laptop. I would really love to dump the big box Windows unit and just work with a MAC Laptop.
At first, I thought the older Mac MBG4 would function as both but if the effort and cost of modifying the unit will not result in the necessary operations for work then I must go in a different direction. I like the MAC operating system as it offers less issues and seem to be more stable than the windows system. What I have noticed that the windows unit I-7 intell is way way faster than the I-7 intell 2010 Imac and they are both 2010 models. It’s just each OP System work differently and I experienced many compatibility issues with programs with the windows 10 where I have had to transfer data to the (home) Imac with no issues work on the data then transfer the data back to the window unit then send the completed work in. Each system has their strengths and weaknesses.
If anyone can suggest a MAC LapTop Unit that will satisfy my needs would be greatly appreciated. I just would like to work with a smaller unit that's portable where the windows unit is a boat anchor, and if I can get portability and work without compatibility issues it would make life easier.
