'Major' spurned a number of chances in Cape Town City's 1-0 victory over Polokwane City in the MTN8 quarter-finals on Saturday afternoon, with some fans venting their frustration on the ex-Kaizer Chiefs man at Cape Town Stadium.
However, McCarthy - Bafana Bafana's record marksman with 32 goals - appreciated Majoro's mobility and dogged determination to get into dangerous positions.
"He just needs to continue doing what he's doing. As a striker when you don't create, when you don't get into positions where you can score goals, that's when you have to worry," said the former FC Porto, Ajax Amsterdam and Blackburn Rovers forward.
"When he gets himself into positions where he can score but doesn't put the ball into the back of the net, it's part of the game. Sometimes your luck is against you, but at least you are creating chances and you are giving your team that option. When you are on your day then those ones go in. He could have easily bagged himself a hat-trick. So I think for him it was important to see that he's still mobile enough to get in behind the defence, and when the team creates chances he's the one on the end of those chances. So as long as he does that, and we create chances and it falls to a striker, then I'm very happy. Then it's just a question of his luck changing and once one goes in then the goals will start rolling in. He must just continue doing that, and once he scores one, he's gonna score 15."
McCarthy, who ended his playing career with Orlando Pirates in 2013, is hoping the club's latest sponsorship deal with SportPesa will avail more funds to sign another hitman, but insists he is not stressed about his options upfront.
"Obviously we have just signed a fat new contract with SportPesa, so hopefully some of that can be coming down and we can invest in buffing up the squad upfront. But I am pretty happy with Major, today [Saturday] was just one of those occasions where it doesn't go for him. I see a little bit of myself in him; a wealth of experience and on his day he can finish anything. So there is no panic really, Major will come right. There's not a problem and Judas [Moseamedi] is not too far off coming back from injury. So that for me there is no reason to panic. To be honest, there are other places in the team where I was panicking, I can't say where."
Regarding potential targets, he added: "I got my eye on some, but it depends if you can get him. Cape Town City's a European team now my friend. They come from overseas, they want to come to South Africa. We are looking, there might be a possibility, we will see. I will find out leading up to the Wits game if possible."
McCarthy's men will travel for their first league game of the season against champions Bidvest Wits on Friday, the same team they will meet in the two-legged MTN8 semi-finals on the weekends of 26/27 August and 9/10 September.
New signing Teko Modise is in fitness race for the upcoming clash at Bidvest Stadium with a groin problem.
